Does anyone know a company that does fuel cell repair.. I think mine might have a tiny leak, and want to get it pressure tested and fixed if need. Any help would be great.
Thanks
Sean

Have you tried Harmon racing? I know the y make new at good prices.
I have used Aero Tech Services Santa Fe Springs, CA twice with excellent results
You can repair leaks in fuel cells with JB Weld

Hartwig Fuel cell repair rebuilds cells and builds new fuel cells for aircraft, helicopters, boats and race cars.
Interesting man to talk to.

Depends on the material - neoprene, the beige ATL stuff, or the Fuel Safe stuff.
If it's Neoprene ATS is your best bet.
The others - if you don't do it yourself you are probably looking at a new cell.
That is not my experience. Years ago I did a test with various glues and sealants - several day's of complete immersion in AVGAS.
The only material unaffected was JB Weld. Everything else either swelled up and lost adhesion or dissolved completely into the gas.
Just curious: what other materials did you test? Did you apply the material to little sample pieces to test the "bond" strength? Seems like a good garage experiment. I did the same "submersion test" with some tubing I wanted to try out for an oiling system and dated the bottle. and left it on a shelf for a long period of time.

Thanks dave - you're correct as usual!
In my experiment I tried several types of silicone gasket maker, jb weld, shoo goo, and some other glues (it's been something like 12 years since I did this) and put them on popsicle sticks (not the best substrate, if I had to do it again I'd use aluminum).
Put them in a paint can submerged in avgas for a week.
The shoo goo and several other adhesives just disappeared, the silicones swelled up and lost adhesion, but the JB was unaffected.
Anyone have any experience with the urethane glues they install windshields with? I used some once when a crack showed up just before a race weekend. It got me thru the weekend, but no idea on long term durability.
Hardman urethane D-50. McMaster part number could be 7493A21. $17,34 for 10 packs. Liquid enough to pull through pin holes with vacuum.
Hey Sean,
Missed you up at Thunderhill. I've had great luck with Aero Tech. reasonable price and quick turn around. The ethanol in the pump fuel seams to just destroy the cell if left with any fuel in it. I now drain my tank after every weekend and run the motor dry.

The Ethanol issue is worse with urethane cells. I have had no issues with the Nitrile rubber cell I got from Eagle. They say with E10 it should last more than 15 years.
BTW, they say to store the Nitrile cells full, and I have done that.
Fuel-cell foam is also an issue with E10. The "normal" foam may degrade, but there is higher-quality foam available. I have not yet had a foam issue in 3 years of use with E10 and the "normal" foam.

The urethane D-50 I think is 7493A21. 3 to 5 minutes work time, remains flexible. Number on package is 04022. You can call their tech line, sometimes they can tell you who makes what they sell.
Thanks Dave. However I'm not sure about the part of McMaster's description that says "Begins to Harden - 2 hrs."
It says "Work Time, 3-5 minutes. Handling Strength, 60 minutes." right on the double/bubble packet it comes in and I can verify that to be true. You have to work fast but it is an excellent product.
