Posted: Tue Jan 01, 2008 8:09 pm Post subject: auxillary fuel tank

Hi All,



Has anyone out there put together their own axillary fuel tank design? I 

am looking for ideas, probably a commercially available plastic tank 

that could be strapped into the baggage area of  an XS mono. I have the 

Singleton fuel tank outlets with vacant taps because I elected to not 

install a sight gage, so I am considering plumbing in there, to the Main 

side, and not siphoning as the Europa design does.Any one doing 

something like that?



I would buy a Europa  aux tank but the cost is just a bit crazy, with 

the dollar so low.

Anybody got one they want to let go?



I am not yet flying, but with the 914 cruising at 16 to 18 grand it 

would seem that 18.5 gallons is a bit limiting? It'd be nice to keep 

going on long XC flights once you are way up there cruising along at 200 

mph TAS.

Kevin, I have designed a composite 110 litre tank to sit in the passenger

seat and to use the existing straps as constraint. It probably doesn't

answer your needs but if so I would be happy to give you more detail. In

this country there are problems with the Europa Long Ranger tank, which I

understand has never got PFA approval. To count as an auxiliary tank (as

opposed to a ferry tank - which introduces its own restrictions) it needs to

pass CSA-VLA regs, which state among other things:

1) the tank must cope with 24kPa (3.481psi) overpressure, that is to say a

tad over 500lbs per sq ft!

2) The restraints must withstand a 9g forward and 3g upward acceleration

loads.

3) The tank filler must be located outside the personnel compartment (on my

design achieved by having a plug in filler funnel with a dog leg so that the

actual filler orifice is outside)

4) Connections must be such that no fuel pump can draw fuel from more than

one tank at  a time.

        My tank has not yet passed PFA/LAA approval although Andy Draper has

made encouraging noises.

        Of course on your side of the pond you can probably ignore such

restrictions, but a loose fuel tank must be one of the least desirable

extras with a nasty landing!

Happy New Year, David Joyce, G-XSDJ

Good luck on that "200 mph cruise speed" Kevin.  I've heard the odd story of 

that kind of speed from time to time, and even willing to put down a bet 

against it.  So far, no takers.

Kevin,

  

 I have been using a portable 25 liter heavy duty marine tank, firmly strapped into the passenger seat (I added an eyebolt at the bottom front wall of the seat for an extra strap), with quickfit connectors, and easily plumbed in to the main tank inlet (aluminum elbow). An automotive fuel pump is also plumbed into the fuel line. Of course, one or more tanks could also go into the baggage area, so long as they are secure. If of real interest, I can look up the details. Thomas Scherer probably used something similar on his flight across the Pacific, also Eric Trombley has a marine tank

 I think David Joyce is preparing for his flight to Australia.

Michel,

  

 The tanks are high strength blow molded construction using molecular weight (whatever that means) polyethylene, colour is

 red.

 Size is 25 liter, measuring 48 x 32 x 28 cm.

 According to my notes it is on website www.mercurypartsexpress.com . It is made in Canada, but I bought my first one in 

the UK, where it is half the price of the Canadian price. They (Mercury Marine) have a dealer locator link. I think I paid

 30 pounds including tax, in Canada it is 100 dollars. The fuel connector is part number 22-816856T3. You also need their

 fuel hose with the quickfit connections.

Hi! Michel/Karl/ Dr David Joyce and all,  

   

At the expense of being a “kill joy” with regards to “Red Marine auxiliary tanks” ……. I believe the guys who were killed doing a 180deg from 300ft take off near San   Francisco in a Europa were using just that kind of tank. Don’t know if there was any conclusions made as to the accident cause or if there was any likely connection but the aircraft pranged into rough grass on the airfield perimeter, the pictures I saw were two body bags and nothing above about 9” high was left of the whole plane.  

   

I have a 9 imp gallon aluminium tank strapped behind the main tank bulkhead which siphons using the Europa style squeeze ball into the main tank. It fills simultaneously with the main tank filler but can be switched off if not required to be filled. It can also be siphoned empty when on the ground.  

“Of course there are some who would say I only needed it due to the Jabiru 3300 gas guzzler!”   

I did satisfy the PFA loading requirements although the actual testing took lots of multiple rope pulleys and a spring balance with mechanical advantage calculations to verify the loads.   

Ivor Phillips can bear witness to a pitfall where the siphon discontinued and about 2 hours later about 30 minutes out of Vitoria (Spain), due to a double wingover maneuver on a photo shoot whilst leaving Majorca, we had a few moments of glorious silence!  He had to do an about turn in his seat and do some rapid hand ball squeezing to ensure enough fuel to make destination.   

The moral to the story is when flying solo with such arrangements ensure the squeeze ball is within reach of the P1 !  

Regards  

Bob Harrison G-PTAG

David,

As I understand it, it was point 3 that prevented PFA approval of the Europa 

Long Ranger tank in the UK; strange as many other a/c in the PFA fleet have 

similar arrangements. Hope you can convince the PFA that the plug-in filler 

funnel will not be ditched at the first opportunity!

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Bob, great "there I was" story.  

  

 I too am very concerned about blow molded plastic tanks for use in an  aircraft.  I can't jump overboard and get in the water fast as I can in a  boat.  I would prefer a properly secured, 9 G, spun molded tank used for  racing (similar to the Europa tank construction), a coated fiberglass  tank or a proper aluminum tank if were my plane.  Yes it's expensive,  and as Bob states, time consuming to build and mount, but worth it.

I recall seeing what appeared to be several standard Europa long ranger 

tanks in a photo on Thomas's website, though it might have been his 

setup for crossing the Atlantic rather than the Pacific (where he may 

have done something differently).



In any event, for myself, I am very leery of jerry-rigging marine tanks 

for our sweet little bird due to questionable crashworthiness, 

particularly in the aftermath of the crash at Livermore, 

notwithstanding my propensity to propose and execute various mods which 

suit my fancy but allow me to remain in my personal comfort zone.

Fred & Kevin, I did ask Thomas what he did for extra fuel tanks and he told

me he had no less than 4 Europa tanks packed in various spots including I

believe 2 in the passenger seat. I did have the impression it would not be

worth asking the PFA /now LAA to approve this particular solution! Regards,

Fred,

  

 I agree, and the installation of almost any auxiliary tank is a dodgy accessory. Also the main tank is not exactly great, is it ? Some of them have developed cracks for no apparent reason, and if I recall, it is made of two sections which are welded together. They also tend to change shape. When I inspected mine a couple of years ago, I noticed that the back wall had buckled inwards, in spite of the enforcement ridges. Andy told me not to worry about it.

 To use the Livermore crash as an example of failing marine tanks is really pure speculation. In such a high impact crash I imagine that any FULL tank would fail, and that the resulting fire was merely incidental in the two fatalities.

 I considered the Europa longrange tank, but it has such an awkward shape for a trigear, making it difficult to secure, and it doesn't look any stronger than what I am using. Again, guesswork, only a real test with tanks full of water and dropped from a certain height would constitute a valid comparison.

 Some builders tell us about their solutions with aluminum tanks, but they don't tell us  how the rest of us might acquire one and with the connection accessories.

 Maybe someone in the business, like Bud Yerly, can manufacture a carbon fibre solution, that is portable, and fits on the seat and the baggage compartment of any Europa. If it also fits other homebuilts, he could generate a nice extra income. It should not hold more than 30 liters, otherwise it is just too heavy to carry.

 The way tanks are secured is just as important as the tank itself. Also, when I use mine, I empty it as soon as there is enough room in the main tank, reducing the fire risk considerably on a (crash)landing.

 Trans-ocean pilots are in a totally different environment, and have to take a calculated risk. Remember Lindbergh ? He practically sat in the middle of a giant fuel tank, with zero forward visibility.

Duncan, Amen to that, although they approved Manuel Querioz's plane with a

fuel tank filler sitting in the middle of the plane! On the other hand I

think that an outside filler position may have something to recommend it if

the natives of Bongoland are going to insist that only they can fill fuel

tanks!

         I didn't mention it but there is also a stipulation that the fuel

pump must not draw fuel from more than one tank at a time, which the

standard Europa tank plumbing doesn't meet. It may be that the LAA have been

taking things a bit more seriously recently as they felt CAA and EASA

breathing more noticeably down their necks!

Karl,



Thank you for your thoughtful post and the several suggestions included 

therein...I couldn't agree with you more. Yes, my mention of Livermore 

is speculation, with "the resulting fire (being) merely incidental in 

the two fatalities", witness Cliff and Mary Shaw's accident (low speed 

stall/spin) but no fire.



As I have a mono, I intend to fit the standard aux. tank.



Your comments re: the main tank are spot on, and as time goes by, 

hopefully we'll all learn more about how to minimize the 

stress-cracking tendencies. I regret not looking closely at the issue 

when I was installing my tank when those little bells were ringing in 

my mind vis a vis the rigid bonding in of a flexible, expandable 

component.



I'm curious as to whether those who have had to replace their main 

tanks have replicated the original directions for tank installation or 

have made adjustments which both provide a robust fit between the CM 

and the tank but nonetheless allow for some tank expansion.

Fred,

 I would not expect the standard tank to  be bonded in rigidly. 

 It sits on a "shelf" on the forward side, is  laterally restrained by a saddle and contained by the 'box' around it. It is not  likely that the apparent bond between the glassed-in supports and tank would  last very long as fuel loads cause the tank to cyclically change  shape.

 It would be a fairly simple matter to debond any  residual adhesion of the tank to the supports, if you are worried about  this.

 plumbed in with the same bulb primer arrangement as the strap in tank and  use  the dry break coupling found on most boats to plug the line in as you  put the wings

 on.  Also (correct me if i am wrong) would the tank and fuel not become part of the  wing dead weight and so not add to G loading weight for those who like to fly at  "Unusual Attitudes"

 from  time to time.

I am a bit confused by your comment "the fuel pump must not draw fuel

from more than one tank at a time, which the standard Europa tank

plumbing doesn't meet".



The Europa 912XS 912S Engine Manual, Issue 6 page 6-3 and 914 Engine

Manual issue 4 Page 5-3 both give layouts with the fuel fed from the

selector valve.  This only allows feed from one tank at a time.

maybe he is thinking that as one tank siphons into the next, then you are in

fact drawing from two tanks at the same time

which i guess if you are being pedantic is correct. Other than that i dont

see either how it is possible to draw from more than one tank

at a time with the standard fuel selector. Does the andair selector have a

"BOTH" position?? (I think it does) i which case then it would be

possible
