Foam or no Foam

Getting a new fuel cell for the puller, just wondering what is better to use , the one's with the foam inside or not ? Thanks

no, foam is a pita when it gets in the complete system...

IF is not required for the class, don't use it. Foam is a safety issue for reducing fuel splash in the event of a crash that causes the tank to split open. Foam is expensive especially when it is recommended to replace every year.

What they said^^^^^. A good friend just went through that mess in his racecar. The foam is nice for controlling fuel slosh when it's NEW....but fuel and time take their toll. The stuff crumbles and travels to EVERY part of the system. Major PITA.

I agree but when you have to take your complete fuel system apart every time to clean the crap out of it even the carb it is not worth it...

if you run alky make sure its out.dont ask how i know........

plus the foam make it hard to look in the tank and tell how much fuel you have in it mine laying in the barn I think it not in the tank anymore anyway

In my opinion if you're running real race gas then use the foam. If the fuel being used has any amount of alcohol in it (pump gas, E85, or race alcohol) then ditch the foam.

I ran Sonoco 114 and the foam started falling apart mid season casuing the little crumbles to go everywhere. After having to clean verything from the tank to the carb, it won't go back in. I swapped from a plastic tank to an aluminum tank last year and the 1st thing I did was to pull the foam out for "storage", it went right into the trash to be stored at the dump!

loose the foam........

Put a new Jaz 22 gallon fuel cell in my '64 Galaxie. Fueled it up, took it out for a ride, got about 5 miles and the engine quit WTF, got plenty of fuel Got it started drove it a couple more miles, same thing Finally got it home, checked the new fuel filter, foam pieces Cleaned it out and took another ride after a few miles the engine wasn't getting the gas, couldn't get over about 2500 rpm. Got it home and fuel filter was clogged . Went to this site and was advised to shitcan the foam, what a mess, even after I siphoned the fuel out. Was looking at the foam later and saw an impression in a piece of the foam the same size as the pickup hose. Evidently the pickup hose was pressing against the foam and sucking it into the filter and decreasing the fuel flow.

Wow , I better check the foam in my fuel tank. I bought it new in '04, I've run Q16 since it was available and never had any problems in my puller. It still looks good but I have a very good filter system.

We used to use foam in our cell for road racing to avoid any fuel slosh and got it from RHS however, we paid for the nitromethane impervious foam which is about 4 times the cost of gasoline foam but, it doesn't break down.
