Gas Problems

I have a 2005 chevy impala and when i go to fill up the tank i cant leave the handle on for awhile by itself its very slow filling any ideas what would cause the restriction.

I have 1985 Ranger that has to be filled really slow because there is a hose inside the filler spout(anti-siphon-maybe) that I forgot to put back on when I replaced the in-tank fuel pump. If I don't trickle the gas into it, it will either trip the nozzle or overflow. I don't know if cars have the same set up for the filler hose or not. If it does, it may have come loose. If you can find a parts breakdown of the fueltank components online or in a Chilton or Haynes manual it should show it . Your local library may have a manual.

I have a 1999 Ford Contour that used to spray gas back at me when filling. I discovered one day that it had a vent hose in the tank that let air out that was plugged with dirt. I replaced the hose and can fill the tank now as fast as I want.

There is a vent valve.. I can't think what it is called exactly now however.. Purge Valve maybe?? Dad is about to replace his for the second time on his 1997 Grand Am.

I'll ask him what it is called later and report back, but most likely that will be your issue.. He's changed them on 4 or 5 cars and a neighbor's truck (all GM products) The truck showed code but seemed to fill normally.

If I recall correctly, it's pretty simple to do.. Takes about a hour or so with average repair skills. The tank usually don't have to be dropped or nothing like that.. But we've never done a impala, that I can recall..

I'll post back later with the correct part name.

Ok that makes sense my check engine light come on
and the code was something like a purge solenoid or
something like that and the impala you can pull the
back seat and there is an access hole right on top
of the tank so it makes it pretty simple to get too
thanks.

Yep.. I think the ones we've done we did from underneath though.. Dad always did them by himself, so I never helped on one to know a whole lot about it.

Dad is out on a job today (retired from the factory, and has to have something to do LOL) but later on I'll find out more.. But sounds like that's what you got going on..

Have you tried another pump, maybe at a different station? There is one pump, where I buy gas, that will not fill my truck properly.
You might also try not inserting the nozzle so deep. Have to be [b:53243f8fe7]careful [/b:53243f8fe7]doing this!!

Typical modern cars have a plastic ball, more or less a ping-pong ball, that acts as a check valve in the filler tube at the tank that floats upward when the tank gets full and stops you from overfilling it.

I have heard of them swelling up from long-term gas exposure or that check system can otherwise jam or fail limiting how fast you can fill the tank. A little debris, piece of a rag, or towel, etc., could easily jam them, as well.

Wife's cousin runs a repair shop in town and was working on a TrailSmasher about that age when I stopped by a few months back, with the same problem, He dropped the tank, and looked at the fill check and filler tube, etc., couldn't see anything wrong, finally gave up and put it all back together and it works normally. Go figure?????

Some where there is a vent. It's neeeded to allow the air in the tank to escape as the fuel begins to occupy the space. It's probably part of the vapor filter system they've been putting on cars since the nineteen eighties. I'd look for a blockage in that mess some where.
