cadieman. i went backout to the garage after you replied on your last answer, so idecided to take the gas lines off the back of the carburetor, both of them, then turn the car over and no gas came out. so does this mean the pump is bad? (even thow i can hear the pump)vince

it runs when u spray it thats fuel.your going to have to replace the fuel pump and hoses to the sending unit.you can check for pump voltage to the pump at the connecter in the rear.use a test light or meter
