Fuel cell size

[huskar]

Rules say fuel cell is to be +/- 2 gallons of stock tank volume.  What are the ramifications of deviating from this rule?  Disqualification?  Penalty Laps?

Ec or dq you cannot gain gallons by paying points

You can run a larger cell than +2, but you would need to add displacement blocks/balls get to "legal" capacity to run in Champcar.  The various series all seem to have a different takes on fuel and depending on your plans, may wish to install a larger cell that would be legal in other series.  We are looking at this with a current build.

Straight to EC or displacement blocks/balls.

Considering the same thing with my work this winter, have you found a reasonably priced 24 gal cell that has FIA approval?

[craig71188]

No, not a new one (depending on how you define "reasonable").  I have in the past stumbled into a "good used" 22 gallon from one of the local round track racers.  Sometimes you can find one with a bladder that is still good.  In another instance, I bought a complete used ATL cell with a good can and top plate (correct rollover protection) for $100 with a bad bladder and then just bought a replacement bladder from ATL - all in it was about 1/2 the cost of a complete new cell.  Both ATL & Fuel Safe are pretty good about "service parts'" for their old cells.

I run a 22 gal  ATL fuel cell and stuff it for Champ. In the TT I have it covered in a sealed box.  What  ever one forgets is the bladder in there cell has the time stamp on it the only way to check is pull ever thing a part . So what I do is take a pic of it and print  it and clear tape it to the top of the sealed box  just makes live in tech line a bit faster .

Were they actually checking the date stamp in CC tech?  We ran an old 2007 Nascar ATL from 2015 to 2018, and never questioned.  If they did check your date I’d be curious to know what region and if they mentioned a age limit.  Last time I read the rule book I did not see it mentioned..

Not in CC but other groups say to follow fuel cell recommendations  from one group

 3.H.9 Fuel System Inspection and Maintenance. All fuel systems and fuel-system components must meet their manufacturer-recommended inspection, certification, recertification, and replacement schedules.   It just makes sense  to keep things up to date . If you feel safe with a 25 year old fuel cell  fine, I just do the pic thing to to keep some techs happy.
