94 F150 Can't fill gas tank
I apparently have a venting problem with my 94 F150 short bed. It just has one tank, but I have to put gas in very slowly or it just shuts the pump off.
Do I have to drop the tank to fix this? Also the gas mileage is about 9 mpg which seems low even for this truck. I have replaced the plugs, O2 sensor and had an overall tuneup. Would the venting problem effect fuel mileage?
