Still don't know, but now I have a 94 zj in my yard that doesn't run. Drip some gas in the tb, and it runs great for a few seconds. Pulled the fuel line.......no fuel coming from the tank. It was reading empty, so I had put 2 gallons in it. I'm not sure if that's just not enough for the pump to pick up, or if I have a bad pump, clogged filter or what yet. Any thoughts or ideas that may same me headache trying to get fuel to the motor?
