I have a 1967 Chevy truck with a 72 350 engine which has crud and rust in
the fuel tank which clogs the filter. I am getting ready to order a
replacement tank. I am probably going to order from LMC as I have ordered
parts from them before.
I changed the fuel cap several years ago to a locking cap and notice
corrosion and rust on the cap when I remove it. I just noticed on the LMC
site they list a non-ECC cap and a ECC fuel cap.
Did I screw up and cause the problem by getting the wrong cap or is it just
the old tank is typically at the end of its life cycle. I don't know which
type cap I put on the truck.
