chase hicklin Posted December 16, 2011 Share Posted December 16, 2011 ive heard that its not worth going the fuel cell route unless its a 100% track car since theirs a lot of maintenance with it and every so often you have to replace the core if anyone has any info on this i would like to hear it or where i can find info on it Quote Link to comment Share on other sites More sharing options...
johnc Posted December 16, 2011 Share Posted December 16, 2011 Fuel cell foam replacement is generally required after 5 years. You also must not run Ethanol in any racing fuel cell unless that cell is specifically designed for alcohol based fuels. Most of this information is available on ATL or Fuel Safe's web sites.

chase hicklin Posted December 16, 2011 Author Share Posted December 16, 2011 thanks i also heard you have to flush the cell every 5,000 miles Quote Link to comment Share on other sites More sharing options...
Dans toy Posted December 16, 2011 Share Posted December 16, 2011 Poly tanks have been used in factory vehicles for more than a decade. They can be damaged easier " punctured or heat related ". If possible route your exhaust away from your tank. On my project I used a Poly tank with aluminum heat shields to help protect from the mufflers that mount on each side of the fuel cell (very close proximity). At some point in the future I may change to aluminum only because I like the mufflers mounting locations. What I have noticed is in stop and go driving there is enough heat that the fuel cell becomes more flexible and may eventually cause the tank to get brittle and crack. Also I have heard comments that a poly tank will emmet fumes. Don't know how true that is. One article I read where the guy had mounted his tank inside the back of the car(bad idea), the fumes were noticeable. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 16, 2011 Share Posted December 16, 2011 thanks i also heard you have to flush the cell every 5,000 miles Not true, but a racing fuel cell (not an aluminum, steel, or poly tank) should never be stored for any length of time with fuel inside.

surpip Posted January 10, 2012 Share Posted January 10, 2012 You dont have to fluch them but most if not all dont come with a filter inside the tank so they tend to fill up with crud after long periods of use witch goes right into your pump so its not a bad idea to check evry once in awhile.

Michael Posted April 18, 2022 Share Posted April 18, 2022 Plan was to start a new fuel cell foam thread, but this thread - despite being 10+ years old - seems ripe for continuation. Triangle Engineering aluminum 20 gallon fuel cell, with foam... bought 23 years ago, sitting sometimes with fuel, mostly without, for about 22 years now, in a humid environment. Probably I should replace the foam, yes? If I don't, at least temporarily, would a standard inline fuel filter handle the "crud"? This is a carbureted engine, no return line, 3/8" feeder line, mechanical pump (driven off of the cam via pushrod), making about 7 psi. I can't find a web page for Triangle Engineering. Are they still in business? Quote Link to comment Share on other sites More sharing options...
