Well, what made me think it is the tank filter is the way it would come and go, especialy when the car pointed up hill, like some crud was floating off and on it. Was really low on fuel also. But If I didn't pump the pedal, it would die, and steady full pedal was going nowhere either, I was not even rolling the power was so bad. I think the variable suction of pumping the pedal was breaking up the clot a little, because it would surge back to full revs with enough power to chirp the Goodyear Eagles on the back. Going to replace all the filters anyhow but do you have to jack the car to get at the tank?
