why is the gas overflowing out of tank when trying to fill it.
What is your question?
Would it be the pressure sensor or the 2-way valve.The air is not being expelled as the gas is going in. If I use a funnel I can fill it a little faster and seems to help to let the air out.
Having the same type of problem with my 96 chevy 3500 truck. Was first told it was my vapor cannister. Now looking into the cannister purge valve. In the meen time, i can still put fuel in tank, but at a very slow pace.
