Gentlemen... (ok, guys) how many vents in our fuel system? I have ID'd the one on top of the tank... a kind of tit sticking up on the back top of the diesel fuel tank. Any more? Reason I asked is that I brilliantly wiped it out for a vent line for fast fill and reconstructed the fill hole for a flatbed and auxiliary tank on the passenger side. Now I am wondering if I have a vacuum problem or is there another vent? No codes or anything... George
