Replacement Foam CUTP
Foam baffling serves two important purposes in a fuel cell. First, it reduces fuel slosh inside the bladder, making for more constant fuel delivery. Second, it prevents electro-static building inside the bladder from igniting and causing an explosion. These dual attributes make foam baffling both an important performance AND safety feature.
There might be chaffing from too much movement of the foam, or internal pumps.
Or it could from non racing fuel. Call and we can help you figure it out so it doesn't happen to
the new foam.
