Had this truck a while . put a fuel pump in it a year ago, everything fine, lowering kit 3 months ago everything is fine. The last three times I filled with fuel the nozzle did not shut off and I had a spill. I checked for a hose off ,something broken on the filler neck and I don't know where to look next . It doesn't leak after the fill ,but I do smell gas sometimes. Anyone been thru this before.. Thanks.
