good shet
It's working , bpught it for my 03 silverado with a new pump I installed, it needed some grease after cleaning the top of the fuel tank off a bit, just a bit on the metal prongs that this seals under because its quite tough to get on without it. Be careful what you thwack it on with to not cause sparks.... hmmm.. thatd be no good.
