The foam usually lasts 5-8 years but the manufacturers recommend changing it
after 5 years. Sort of depends on the temperature, fuel type, etc. of the
environments it's in. Mine lasted 17 years before it crystallized - I don't
recommend you let this happen... The car was always garaged. The rubber
bladder is really what keeps the gas in - a tight fit won't hurt anything.
You already got your answer on the MPG.

Subject: ? re fuel cell/ MPG
How often does the foam in the fuel cell have to be changed? the ATL web
site doesn't
specify. mine is 3yrs old.
Also, I tried to remove the cell (it's the molded ATL plastic type) only to
discover that swelling caused it to be an overly tight fit. I managed to
get it
out intact but, does this tight fit cause any ill effect? The container
didn't
split.
Also, noted that while flushing out the fuel with water, the cap leaked when
I turned
it upside down. Hopefully another washer under the cap will help seal
better.
Finally, doest anyone have a guesstimate for MPG for a race engine? My
stock engine
used half a tank per race. It's a lotus TC.
thanks
christopher
