Why does my gas tank overflow when it's not full?
This just started recently but when
I'm pumping gas no matter how
much was in there before I pumped it
it squirts back out as if it's already
full. I can fill it up eventually but it
takes forever. I've heard of this
happening on new cars but not on
older ones. I also know I'm gonna
need a fuel pump at some point
cause it takes a few starts to keep it
running when it's cold, not sure if it's
related to the gas tank issue. If
anyone can help me solve this
problem I would greatly appreciate it.
there is a problem with the fuel tank vent hose.
Sounds like the vent valve for the EVAP system is stuck closed. Since it's an OBD I vehicle it will not set a trouble code or cause the check engine light to come on. As for the starting issue, check the choke plate on the carburetor. When the engine is cold press the gas pedal to the floor once and release. Remove the top of the air cleaner. The choke plate should be fully closed. HTH. -Jim
I have the same issue with my 2010 Malibu. How much does the fuel tank vent hose cost to get fixed?
I'm dealing with this same issue with my 1988 cutlass supreme. I've changed my gas tank out and the three rubber lines coming from the fuel sending unit, before it turns back into steel lines. So where is this vent hose supposed to be ?
Drive 2017 Malibu new one everytime go fill up gas comes back out thinking no way it can be full but check gas gauge it will say full thinking could Malibu run good on gas
