Mahesh,



Unlike Richard Pike,  I have two six gal tanks in the conventional location behind the jump seat as my main tanks, and use two auxiliary six gal. tanks as needed depending on the length of the trip, on the jump seat location.  I transfer fuel in flight from the auxiliary tanks to the main tanks with a second pulse pump by simply opening a valve.  I'd really hate to permanently give up the space behind the pilot's seat for carrying "other freight" by putting my main tanks there.



If your plane  flies like mine does, you will notice only a  very slight difference with the extra tanks.  Slightly longer take-off roll,  slightly less climb performance,  slightly higher fuel burn,  slightly greater  turbulence stability, slightly greater risk of bending the landing gear on a hard landing ,,,,,,,,,,,, and a significantly greater urgency to empty the bladder.

 Hello Richard,

 Thanks for your input and the picture posted.

 I will surely take your suggestion and calculate the W and B and move the two 6 gallon tank accordingly.

 

 Will appreciate if you can send me additional pictures info, if you have them. What is your present configuration of the tanks? Did you find the FS-2 flight characteristics change after adding the additional fuel tanks?? I do anticipate a longer roll during take off.

 

 Thanks,

 Mahesh

That looks very nice Richard.  Almost makes me want to clean up my floor

 Since FSDO has not yet returned the Airworthiness Certificate (which was collected after the crash, pending the rebuild) we haven't flown it yet, so no info to share.

 

 But here is what it looks like, the only mods were a couple diagonals welded from what was the front sling seat mount/cross brace to the side vertical tubes, and a length of 3/8" tubing between the two tanks and up to the upper cross brace to help secure the tanks. The original gas tank tray now sits on those lower two diagonal tubes. Also added a cross piece to attach to the carrying handles on the top of the tanks. Works well, hardly any wiggles, very secure.

 

 Since I wanted the fuel tank pickups to come out of the top of the tanks, the primer bulb was necessary. The Facet pump (visible below the tray, center) will not pull fuel without a prime, hence the primer bulb. 

 

 Downstream of the primer bulb is my "poor man's gascolator" (details here: http://www.bcchapel.org/pages/0003/pg13.html) and you can sort of see the line going to the quick drain valve off to the left of the fuselage.

 

 The right tank in the picture has a JC Whitney gas gauge sender in it, after we take the film off the Lexan I take a picture of how it is installed.

 

 The black thing on the front of the left tank is the battery box for the ANR headset.

 

 More pictures later.

Richard/All

  

 I looked at your poor man's gascolator again and noticed you use one of those rubber bushings that you refuse to put in your fuel tanks. You seem to be inconsistent. Properly installed (maybe I have been lucky) they don't leak. I carefully drill with a step drill and debur the holes.

   

 Any way you can get a certified style gascolator at Great Plains Aircraft for under $40 and not have to use those as you say leaky rubber bushings at all.

  

 I also use safety wire clamps but I have a tool I picked up at Oshkosh that makes a fine safety wire clamp and doesn't have as much of a sharp pointy end. I have been replacing all my clamps on my airplane with them and have been real happy with them. They end up being much lighter than the traditional clamps. It is surprising. I have been throwing the old clamps in a box as I replace them and I have saved a few pounds already. I likely have more clamps than normal but every bit helps.

Don't remember saying anything about leaky rubber bushings, maybe I did, didn't see it anywhere. The reason we put them up top is because the six gallon tanks seemed to be a bit thinner wall thickness than the five gallons tanks that were in there before. Maybe not, but they seemed that way to me. 



Don't remember refusing to use rubber bushings on the bottom of fuel tanks, we used the rubber bushings in the underside of the previous five gallon tanks and they worked fine, but somehow I just didn't feel too good about doing the same thing with the six gallon tanks. 



And besides, doing the safety wiring on the plumbing is so much easier when things are up top...



Roger on the box full of heavy old hose clamps... Me too.

Richard,



Will it have a cockpit heater?

Won't need one. By the time FSDO gets around to inspecting it, it will be warm again.
