Fuel pump replace questions
Original fuel pumps are shot. Have read about replacing . . but having the old one out I have questions - 1) The 2 pumps are molded together as a unit and are mounted on a spring loaded tube from which I see NO WAY to remove them . There is a square metal tab spot welded to the bottom of the tube making them non-removeable . 2) if I somehow solve this spring loaded tube problem, how do I convert to 2 individual fuel pumps ?
I am completely lost as how to do this fuel pump replacement . All help appreciated . . . attached picture shows pen pointing to spot welded tab on bottom of spring loaded tube. |

Re: Fuel pump replace questions
feeling like a real dummy here . . . I see that the pumps slide down into a solid joined plastic case so I only have 1 question left . . . Does anybody know who to order the filter / socks from and proper p/n#s ? Thanks to all .

Re: Fuel pump replace questions
Cut the zip ties located on top of each pump and they will lift out of the plastic housing.
See my recent post "Fuel pumps" for info about parts. Last edited by CamP; 07-25-2020 at 12:06 AM. |

Re: Fuel pump replace questions
Very pleases y'all found some diverse sources for parts. It is always a good thing to have some choices for parts, especially since so much stuff is made in China theeze dayz. But, FYI, case y'all are new here, Jerry, aka Jerry's Gaskets is a Registry sponsor, and long time supporter of our cars. Keeping our cars running would be a lot more "challenging" if not for Jerry Downey.

And you will install the pumps in the opposite position as you removed them. Make sure the wire harness on both pumps is attached so you don't have to do the job twice 😂! Been there done that... Besides that it is an easy job.

First, exactly what kind of clamps do you have in mind? Secondly, I don't understand how I would install the pumps in the opposite direction. Thanks! |

Re: Fuel pump replace questions
I actually documented some of the steps when I did my fuel pumps last year: https://zuggszr1.com/gallery
