I took the fuel cell enclosure apart on my FE and there was a fair amount of crud inside the enclosure (sand, dirt, tire rubber pickup, etc.). This gunk, combined with the cell just rubbing against the aluminum enclosure, resulted in the cell wearing on its bottom and selected corners. Luckily, however, it's not leaking and the wear doesn't seem too serious.
Does anyone line the interior of the aluminum enclosure to prevent abrasion on the cell? If so, what material is used?
I was thinking of sealing the enclosure joints with fuel tank sealant (http://www.aircraftspruce.com/catalo...es/ac236b4.php) to keep out dirt, and then lining the enclosure with something like wool felt.
I could use rubber as a liner, but I'm worried it may break down and turn to goo if the cell ever leaks. I guess I could go with Viton, but that's probably quite expensive.
Thanks,
Jon
