CAR QUESTIONS TAKEN FROM
OUR WEEKLY TALK RADIO SHOW
Dear Motor Medics,
I’m in need of repair advice. My wife has a problem with her 2002 Pontiac Grand Am and it is in my best interest to get it repaired for her before winter. The problem with the car is when we try to fill the fuel tank. No matter how slow we fill the tank the pump handle clicks off. We have to get it at just the right angle and speed to get any fuel into the car and to fill the tank literally takes us 15 minutes. You can see the dilemma of getting this repaired before winter. If I don’t get it repaired it looks like I will be in charge of the tank fillings.

Can I interest you in a slightly used parka? You are not alone in your slow fuel tank filling blues. GM vehicles seem to get hit the hardest with this issue because of the design of the fuel tank vent system but others have it as well. When a fuel tank is being filled it must vent properly or the fuel will not flow into it. The tank has a vapor vent system that consists of a vent valve, rollover valve, and emissions canister. It is common for the vent valve or canister to become clogged with dust, more so if you frequently drive on gravel roads. Have a shop inspect it and replace the failed components.
Take care, the Motor Medics
