Owned a 2004 a year ago, it left me out of gas 4 times so i finally installed a new pump/sending unit. After doing so the guage would not read above half a tank no matter how full the tank was. Well sold that one and ended up getting another great deal on a another 2004 model. The owner of it had to put in a new fuel pump becuase the actual pump went out and stranded his wife..........well its doing the exact same thing as my old one. Guage is not at all acurrate and wont read above half a tank, the trip distance to empty is all over the place also. I know they recalled the 2005 and up on these and makes me very angry that they didnt do the 2004s for the exact same problems and updated the fuel sending units. Well has anyone bought a fuel pump that will actually work correctly without going to a factory Nissan Unit? i bought mine from 1A auto and not sure where the previous owner bought his pump but i know its an after market ? Have any of you guys had any luck with this issue?

I know someone has had to have had good luck with aftermarket replacements ??? Anyone ???

Did you change the fuel sending unit?

I got this one a few months ago because the price dropped to $88 - but i didn't install it yet so I can't say if it's any good. All but one Amazon review is good. I got it because my fuel gauge only goes above 3/4 full moons and I figured at 160K a new pump couldn't hurt. Waiting till I can drive the warm weather car before I put it in - so I should have an answer in a month or so.

Yes, basically all the fuel pumps i have seen have a fuel sending unit already built in to the new unit. This is where i think the problem is.....the aftermarket not sending the right signals to the gauge. I get a P0461 code come up too when i fill the tank totally full.
