changing the fuel pump?

Can someone give me some advice on replacing the fuel pump in my 91 automatic metro?

Thanks!

You must pull the tank and remove the sending unit assy. Make sure you spray the screws hold the sending unit down with WD 40 and hope they come right out.

Another trick that will make your job easier...Empty the fuel tank first. There are a few ways to do this. 1. Drive the car if you can, this is probably the easiest way. 2. Try to siphen the tank. I have never been able to successfully get a siphen hose far enough into the tank to get it empty. Maybe others on the forum have a good way of doing this. 3. Remove the larger of the two fuel lines from the throttle body and extend it using another length of hose and a double male hose fitting. Then jumper the fuel pump relay to run the fuel pump constantly when the key is turned on. Allow the pump to run until the tank is empty.

Draining the tank will make the tank less heavy when you are removing it from the under side of the car. This is especially important if you are working alone on a car that is up on jack stands and you are laying on a creeper. If you want more details on jumpering the fuel pump relay, let me know and I will go into more detail. Good luck!

Heh. Steps 1 and 3 may be impossible if the old fuel pump doesn't work. I would also look for a drain plug. I'm not TOO familier with Geo Metros, but some cars do have a drain plug on the gas tank.

Good point on the bad fuel pump. I have only seen two or three fuel pumps go bad on the Metro's, but these would still pump good enough to get rid of the fuel in the tank. This jumping of the fuel pump idea may sound hard but its actually very easy and doesn't take very long...as long as you have a good battery.

Well, if not the fuel pump -- what else could it be? it sure wasnt the fuel filter!

Also check the connector undsr the back seat that goes to the pump. It could be corroded. I found this to be the case on a 92 I was working on a few years ago. It is white but I do no remeber what the colors of the wires are. I think it was the only one under the seat on the passenger side.
