By yourself? Plan on it taking most of the day. Be sure your fuel tank is almost empty before you start. This is if your fuel pump is in the tank like it is on my 91 CRX. Also, be sure the replacement fuel screen that attaches to the pump is exactly like the old one. I got a fuel pump from Pep Boys. The new inlet screen did not sit on the bottom of the tank when installed because it was a little shorter than the original. It ran out of gas at about 1/4 of a tank. I had to drop the tank again, take the damn thing back out and put the original fuel inlet screen on the new pump. Talking about P.O.'d.
