Gas Tank Whoosh?
Everytime I take the gas cap off to fuel up, I get this tremendous sucking sound from my fuel tank. It makes no difference if the tank is empty or 3/4 full. What causes this? Is this normal? What's the advantages of a vented cap?
Thanks

Do all caps need to be vented? The old gas cap on my 74 said "vented" on it (also had no gasket on it). The one I put on last night (from Zip) is unvented. Haven't had a chance to drive with the new cap on it. Is my gas tank going to implode??? :eek: :eek: :eek:

my beretta used to do that. mostly when i was running on fumes in summer. haven't heard it with the Vette yet. I agree with the need for a vented plug. I don't think the tank will implode, but it can't be good. I wonder, could that effect the fuel be pumped out by lowering the pumped pressure?
