    Fuel pump question

    Got this 88' Sedan Deville {4.5 liter} that I resently purchased for my mother inlaw. It doesnt have a gas needle to tell me how much gas is in it so she has to rely on the digital reading to tell her how many gallons are left. OK. The digital reading is always on E no matter how much gas she puts in. An off road mechanic stated it was the float on the fuel pump. I think the same thing.

    The questions I need answered are:

    What do you think it is

    What year Devilles can I get a used fuel pump from at the junk yard, that would fit

    Is there a fuse that controls the fuel reading that I should check first

    I think your mechanic is right. (Will miracles never cease?)

    I would not go to a junk yard if I were you; tearing down your tank and replacing the fuel pump is a pain in the a** and not having to do it more than once a decade is worth the $250 for a new fuel pump.

    Just my two cents.

    your two cents is 2004 because because it is alot of work.

    I have taken down a tank before but she would be the one spending the $250.00 and the car has 233,000 + on it. So Im not sure if she wants to keep it past 1 or 2 years from now. Its just something to get her around until she can get what she really wants. I can put it in, If shes willing to get the part.

    Re: Fuel pump question

    i just did that repair, although the float and sending unit were good (just had to replace the pump itself)

    for a few hours of work and a $50 part.

    i asked several mechanics before i did mine and they all quoted me $300 to $600 for parts and labor.

    it's a pain but not hard to do yourself if you have the time.

    Re: Fuel pump question

    Yeah, Ive done it before on another type of car. Its basically the same kind of labor. Im thinking of just getting the part from a salvage yard and spending a few hour on a weekend.

    I wouldnt mind getting one from a newer car if I knew which ones fit. Its an 88' Deville 4.5L. would you happen to know what other year fuel pump would work??

    Oh OK.. I looked on the computer and found that AutoZone has a new pump for $60.00 .

    I looked at www.AutoZone.com

    Re: Fuel pump question

    i went to autozone and after all of the parts (pump, filter, and strainer)it came out to $73.

    when you do it, just double check the sending unit and the electrical connections going to the tank before you remount the tank (which i forgot to do) to eliminate any issues after putting the new pump in.

    I thought all that stuff was connected to the pump.

    Re: Fuel pump question

    Perhaps this is a year-of-Caddy issue? I bought my '94's new fuel pump at NAPA for just under $300, so I know I got reemed a little, but the quote I got at Auto Zone was not that much cheaper--$250 or better. NAPA could just get the pump quicker, and I needed the car back ASAP. But it was definitely an expensive part, for aftermarket.

    actually i forgot to check the harness coming off the car to the tank. but i really just threw everything together, thats why i suggested checking both sides (which i didn't do).
