HD: Sorry guy, your going to have to pull the tank out and clean it out. All your doing when you back blow the lines is push debris out of and away from the sock on the sender fuel pickup. When you start the engine again all that crap goes right back into the sock and plugs it again. Pull the tank and remove the sending unit and take a good look in there. I think you may find a new tank and possibly sender are in order. As you well know rusting of the tanks and tank supports is a huge issue with our trucks. I'm on my second set of brackets and third pair of tanks now.:chevy: Jim

if youre lucky you may be able to take your gas tank to a radiator shop and have it boiled out and soldered otherwise james is right

Bob, your right, that is an option, but by the time your done screwing around you might just as well replace the tank(s) and hangers. In the long run it's more cost effective and less labor intensive, right?:chevy: Jim
