Would like to hear from anyone that has installed a fuel flow indicator on a CJ -6 on where they installed the transducer and how well  it's working in that location. 

 

 Also FYI Pacific Coast Avionics has the JPI fuel flow FP 450 on sale ( $ 345 )   The following is from their ad: 

 

    Special price - $495.00    
Displays: Total Fuel Used, Fuel Remaining, Endurance in Hours and Minutes, Fuel Required to Waypoint, Fuel Reserve at Waypoint, Nautical MPG    
Works with Shadin or Hoskins System    
Continuous display of fuel burn    
$150 Mail-In Rebate Through December 15, 2007     

*FREE 2-day shipping

I believe you will need the high flow transducer as well. This will inflate the price considerably.

Walt,

 I ran a Hoskins FT101 in my CJ and also later in my Yak 18 / CJ5 and it worked great.  This ad is a little misleading because this is not a complete system they are offering.  You will need to also buy a Flow Scan or some such "fail safe" transducer to get the signal to the JPI unit.  FYI the transducer used in most marine fuel flow units are exactly the same as the aircraft type.  Both are "fail safe".  I have sold a few of the marine units over the years and they work great also and the cost is about 400.00 complete, head and transducer. 

 

 Sorry for the long winded oratory about the water filter, I guess I mis understood.  There is a "sock" type filter out there, but it robs you of one inch of MP.   Do you have a 10 micron oil filter installed?  If not you should it will (IMHO) gain you more benefit unless you operate in a extremely dirty environment.

 

 Best,

 Doug

Just so that you know ...the JPI unit on sale at Pacific is complete. I 

know because I bought one and it came with the transducer, harness and 

the indicator. I also spoke with JPI and they told me that this one is 

good to over 45 GPH so it should be fine for the CJ with the stock motor.



I would like to know where people have mounted the transducer ( sender ) 

normally they like to be horizontal in a straight run of pipe to work 

best ... where have you guy's mounted yours?



Thanks,

Walt

I mounted mine just up stream of the inlet to the carburetor.

How hard is it to get the fitting to mount standard threads to metric

The ad for the JPI 450 includes a Floscan 201 transducer,  which is not suitable for our high-end fuel flows.  See Gulf Coast  Avionics' web site.  You will need a Floscan #231 and I have asked them to  swap the 201 for a 231.  I also bought a Floscan 231 direct from the  Floscan web site for $110.00.  With shipping and handling,  $127.

Walt and Dennis,

 I stand corrected the PCA system is complete and is a very good buy if supplied with the proper transducer. 

 

 Also, I sent my Hoskins Fuel flow to Scandia Aerospace to have it checked and repaired after it went TU.  Scandia found a dead transducer and hooked me over $350.00 for a new one.  A month later Joe Cook was telling me about a marine fuel flow that he had just put in his CJ and I remarked that it might be low cost ($400.00) but I doubted the transducer was a aircraft quality "fail safe" unit.  He called me back after checking and not only was it made by Flow Scan it was the EXACT same part number as the Flow Scan transducer that Scandia had just sold me.  The only difference was that the marine unit did not have "TSO" after the part number.    Live and learn.

 

 Always yakin,

 Doug

If I remember right the Flowscan transducers are  manufactured in Washington or Oregon.  I used them on an engine dyno when  we were racing and they were reliable but they are sensitive to the plumbing  before and after the transducer.  They like a straight run before and after  the sensor to cut down on turbulence.  We used them for alcohol and gas  with no problems.

Walt;

  About three years ago when there was the price war between JPI and ECI; I bough a JPI for my Cessna and was quite satisfiied.  Because the CJ-6 is "fuel capacity challenged" I bought one (at a higher price a few months later) and installed it in N-96YK. Since then, both have operated flawlessly.......register fuel between fillups close to + or - 1 gallon on 35 to 70 gallon fillups.  (Aircraft dependent). 

  The Cessna installation (C-182) allowed for more close compliance with the horizontal/straight line intallation as suggested by JPI; the Nanchange installation was not in compliance with the JPI requirements, but seems to not matter.  

  I am on a job away from the Nanchang for 3 weeks; but can send pics of the Nanchang installation if you are interested.  Can't remember the specifics at this time of the installation; but DO know that I trust the fuel flow indicatior MUCH more than I trust the fuel gauges.       Be a better pen pal.  [quote][b]

, Roger,  I've got a JPI I'm about to put into a YAK 50 and would appreciate having pictures of your installation. Right off I have a question re the type of hose fittings you have used . Did you go with U.S. sized fittings and what brand of fuel hose is installed in the CJ? Is it Chinese metric or US? Please feel free to include any suggestions you think helpful. Thanks in advance.

Here is a the fitting I am ordering for the installation of  the JPI 450/Floscan transducer.  It is a -6 AN fitting; 1/4NPT to 3/8" hose  barb.

 Available at http://www.jegs.com/webapp/wcs/stores/servlet/KeywordSearchCmd?storeId=10001&catalogId=10002&langId=-1&N=0&Ntt=663010&Ntk=all&Nty=1&D=663010&Ntx=mode%2Bmatchallany&Dx=mode%2Bmatchallany&searchTerm=663010

Dennis made a statement that the JPI  450 fuel flow that's on sale comes 

with a low flow rate transducer and that is incorrect.



I spoke with them prior to ordering mine and they told me it would be 

fine in the CJ . After reading Dennis post I decided to open the package 

and take a look at just what I got.

I received the AS 407B transducer which has a labeled flow rate of 0.6 

to 60 GPH .....I think that should do the trick. 

So.....if your thinking about a fuel flow this is as good as it gets .

The Floscan -231 transducer has one of the lowest in line pressures of 

any of  the other dash numbers.  This is the amount of pressure required 

to turn the rotor.  This is important in case of a elect failure to 

assure ample fuel to the engine.  I am very sure most any dash number 

would work but the -231 IMHO is the best suited for the CJ, 285 or 360 hp.



Always Yakin,

Doug

Walt, I don't believe I said it came with a "low flow rate transducer".  I 

do believe what I said was it came with a model 201 transducer, which in 

fact comes in three different versions; 201A, 201B and 201C.  These are the 

TSO'd transducers listed on the Floscan web site.  I was unable to determine 

from the JPI web site which transducer the kit comes with.  Since the JPI 

450 is spec'd for aviation and STC's exist, the transducer must be TSO'd. 

So, I assumed it must come with a model 201 of some kind.  As for a 407 

transducer, that model is not listed on the Floscan web site nor is it 

listed, including on the Accessories page of the Floscan site or on the JPI 

web site for the JPI 450.   To be on the safe side, I made the assumption 

(right or wrong) it came with a 201A which has a .3-30 GPH flow rate, 

according to the chart on the Floscan web site.  If it came with the 201B, 

then it would be perfect for our installations because the 201B has a 

published flow rate of .6-60 GPH.  If a person tries to order any model 201 

directly from Floscan, they will tell you to order if from one of the listed 

distributors.  They will not sell it direct.  Believe me, I tried this. 

HOWEVER, if you want to order the marine version (which is not TSO'd), you 

can order the model 231 which, according to Floscan has a similar flow rate 

as the aviation model 201B AND you can purchase it directly from Floscan for 

$110.00 plus shipping of course.
