Just maintaince items cross my mind. Your truck doesnt ever suck air every now and then? Tank selector valve works good? Lights are all working and in order?
The only other issue I ran into was I had a loose return line cap that leaked a little fuel. Tried to fix that at my uncles in So-Cal, ended up shattering the cap (I put a socket on it and pushed down, worked for me before, guess the plastic was to brittle). Had to go get a whole new return line kit from Napa....for roughly $100. Wish I had another on me at that point!
