    Anybody else out there have problems with puttin gas in their trucks? I have to for all intensive purposes trickle the gas in. Takes me about 25 minutes to go from empty to full. /forums/images/graemlins/eek.gif This really sucks. Any ideas? Thanks is advance.

    Yeah, I know what you're talking about. Try pointing the nozzle up a little bit and don't push it all the way in. If I put it all the way in I can't fill it at full flow. Chances are if you have a problem then a 98-01 Cavalier will have the same problem. The problem is that the head senses too much pressure. Cavaliers don't vent fast enough. Our trucks appear to have the same problem in combination with the filler tube bends. The other problem is the vent which "T"s into the filler tube pretty low in the filler tube. It seems it just can't escape fast enough. Someday I'll drill the holes a little bigger in the thing the gas cap screws into.

    Inverting the entire pump handle always works for me, and I know almost all of these trucks have this problem. I know this sounds nuts, but try it, It works.

    Full flow?? /forums/images/graemlins/confused.gif That results in about 5 seconds until the nozzle cuts off. It's almost like there's a ping pong ball in the neck right at the inlet to the tank. I poked a wire down the line and it seemed to make it to the 90 into the tank. Hope that might help.

    the last couple of trucks ive had have been modified by previous owners, they knocked out the spring loaded door and cut more of the metal out of the way to fully open up the opening, seems to help noticeably, i just dont put the nozzle all the way down into the openinga buddy of mine with a diesel 82 has a hell of a time filling with the pump nozzle, i feel sorry for him
