Gas Tank Vacuum
Seems like there's a lot more vacuum then normal
when removing the gas cap? 1990 w/40k miles No codes, runs fine. Always has passed emissions where they check gas cap as part of check. Fuel level in tank makes no difference. None of the hoses/wiring etc have ever been messed with. Just replaced fuel pumps, but it did this previously. Gas cap? Evap cannister solenoid valve? Imagination? |

What is kind of scary is when the fuel blows out with air pressure change! It happens just not often! |

Re: Gas Tank Vacuum
If you disconnect the Fuel Rail Fuel Lines, ALWAYS remove the gas cap or you will get a continue dripping of fuel out of the fuel lines as long as they are disconnected from the fuel rail.
