I'VE HEARD OF USING THE SMALL WIFFLE PRACTICE GOLF BALLS. NEVER TRIED IT BUT HEARD IT WORKS.

Save all your old plastic bottles from anti freeze, oil... ect and cut the tops and bottoms off of them. A guy that used to own the local race shop told me that's what he did for years.I am even using the two liter soda bottles when I'm done with them ( just make shure there cleaned and all glue removed).

Someone mentioned drain tile. That is the plastic hose that you put on the end of a gutter to distribute water evenly. You can get em with or without holes.

That is what I did. I went and bought about 20 feet for the cell I am running. I think it is a 20 or 22 gal. It cost me $10.

What I did to get it in the cell was spilt it down the middle and roll it together so it would fit in the hole.

Stand em up and expand them. On the side where you see the pickup, lay them down on the side.

Just like odb said,just use twist ties to hold 'em.

THE POINT OF USEING FOAM IS TO HELP KEEP THE FUEL FROM GOING ALL OVER IN A HURRY IF YOU RUPTURE YOUR CELL!!!!!

ALL OF THE ABOVE MENTIONED WILL NOT HELP THAT IN THE LEAST. BUY SOME FOAM.....

what about filling the cell whit wiffle balls and a layer of sponge on top?

But there is only so much fuel that the foam will soak up. Once it reaches it full capacity all the rest will roll out of the cell onto the ground. I just depends on how big and where the hole is.

This sounds like a good task for the MythBusters. Somebody email discovery channel.

I do not run anything in my fuel cell. Just the straight methanol. I have heard that foam can dry out and get caught in your lines, and cause a lot of problems. I have run gas and methanol, and never used foam.

then hoss your are a danger to yourself and everyone who races against you. Why not just get a big jug if your not gonna run a cell properly. My biggest gripe is with tracks who will tech every bolt and cranny but never
look at the driver safety equipment.I love it but this sport kills and maims people every week somewhere in the usa. Heck our track uses the expended extinguishers for stools for the corner people.

I 2nd that, if your looking for a cheaper alternative to fuel cell foam you should probably not be racing anything at this time in your life.

Fuel cell foam to soak up fuel to keep it in the cell?Sounds like a wick that'll burn all night.

Foam might make a difference in a 22gal cell but in the smaller ones like my 12gal I havent noticed any difference on either dirt or asphalt I dont miss the chunks of foam that come through the filter as the foam deteriorates as the fuel breaks it down. Eddie

I'm with jay, The foam is for slosh control not to soak it up. If it was there to soak it up you would run out of fuel with a couple laps to go because it would be suspended in the foam.

i dont run foam but i do run a rollover valve, and a flapper valve. "JAZ" 22 gallon cell. To be perfectly honest, unless we run a REAL fuel cell (w/bladder) were not putting safety first anyway. ATL, FUEL SAFE, etc start at about 500.00 bucks. Im quilty too.

The foam only acts to control the slosh in the cell. Once you put it in and add fuel of any sort it is saturated and ain't gonna soak up nothing more after that. Now if you mounted it outside the cell where fuel was gonna go after it left the cell it would absorb something because it would be dry to that point. Pretty dumb huh? Any baffle system will work, just run a rollover valve so if you flip nothing comes out.

I agree completely with the slosh control theory. I run a 32 gal cell. Yes 32 gal. I have been told by many greatly experienced racers that IF you run foam, the bigger the cell - the more often you have to by new foam because it does deteriorate. I know guys who spent an entire season chasing problems that came back to the old foam running through the fuel system. Once saturated, it won't soak up any more. Someone already said that. I feel safe and I drive so the other racer is safe too. Heck, I used to run cars with stock gas tanks. Never had one of those come apart. The fuel cell shouldn't either.

Thats why I dont run any foam it deteriorates from the fuel I agree with the slosh therory but once i seen the foam coming through into my filter out it came. Eddie

I also believe you cannot run the foam if your using alchohol.

drop a cup of water on the floor, look at the mess and spread.

now soak up the same cup full of water with a sponge and drop the soaked sponge..


I cant believe some of the stuff said on here, good luck to all of you.

Jay from your link.

Answer: The foam is one of the most important components of a fuel cell. It is designed to reduce the slosh of the fuel and the chance of an explosion by reducing the air volume in the cell. If the cell does ignite internally, the foam absorbs the expansion and the energy of the explosion. At that point, the oxygen is used up and the flames go out. The cell must be filled with at least 80% foam to perform effectively. The foam only requires 3% of your total capacity.

Why are you guys using such massive fuel cells? Do you run races that require 20, 25 and even 32 gallons of fuel?

I use an 8 gallon cell because it seems like one of the safest things you can do is carry less gasoline. A smaller cell helps keep the set up more consistent as well because the range between full of fuel and empty is a lot smaller.

UNVRNO, pour that cup on a stick of fuel cell foam & see how much stays in the foam. Hardly none.

hey, most the time if you rupture a cell, its crushed right?
what happens to wet foam when it is compressed?
it runs right out of it.
my advice is dont run fuel cell foam, and buy a good cell.

Western - I run Enduro races. 200 laps or 3 hours. Whichever comes first. Thus, the biggest cell allowed by the rules.

Wow, that's a long race. I wish they'd run races like that here in Illinois.

The safety issue is important but i think it's overkill for stock type cars to run really expensive cells and devices designed for cars reaching very fast speeds on tracks longer than 3/8's to a 1/2 mile.Can't hurt but properly protected cells should be fine in my opinion.

i dont run foam but.. i did build my can out of stainless steel due to the fact it wont tear as easy. stainless doesnt spark like carbon steel also. its just tougher all the way around.
