Default How do you change a fuel pump?

I'm searching but there is a lot to filter through and I haven't found a step by step yet. Pictures would help.

There is a wire that goes from the battery box to the back of the car. I followed it and it goes by the spare tire and disappears. I think the wire is lose and I want to go in to see the connection. Is there an easy way or procedure to do it?

I need to move the car and it doesn't even have an owner's manual.

Its a 82 with carburetor. If I pour gas in the carb it fires up but then dies out.

I've been having issues while driving so i think its the connection to the fuel pump.

IIRC, 82 was Cross-Fire injection. Fuel pump is in the tank.

thats good to know. after the original post I did find directions on google. but not detailed. I guess I just have to follow wires to check the connections.

When i first went to get the car started i put in a gallon of gas in the tank and cranked it many times. No start.

I put gas in the carb and it started and died out.

I googled some more and decided to listen at the fill hole. I heard the pump running. I put in about 2 more gallons of gas and more gas in the carb.

It started and kept running on the second try. Weird....


(how long does it take for gas to go from the tank to the engine?)

I would check the pump presure at the fuel line at the carb. Most carberator with electric fuel pumps are between 4 to 7 PSI. I have installed electric fuel pumps on carberated cars before. I do not know what the PSI from the early Throttle Body Fuel injection systems were but you should know the PSI output to resolve the problem with the conversion.

I looked it up for TBI Fuel pumps they have an output between 10 to 17 PSI in the early model cars. Your float might not handle the extra pressure in the Carberator unless they installed an inline fuel pump under the hood somewhere.
