Fuel Pump Not Pumping
After putting 5 gallons of gas in the tank and trying to crank the jeep for the first time in 8 months I have a fuel delivery problem. The tank was off and the fuel sender was inspected back in April. I cleaned the sender rheostat and replaced the short hose between the pump and the output tube. I did not replace the pump since it had a 2004 date code on it and was working fine at the time.
Today I hook the pump directly to a spare battery and can hear it running, but no gas comes out of the fuel line before the filter. Took the power off and applied compressed air to the fuel line. I could hear it bubbling inside the tank. Having forgotten to remove the gas cap, fuel rushed out of the line because the tank was pressurized. Guessing there is not pinched hose or obstruction I applied power and still no flow.
