    Fuel Pump Upgrade

    This is for those who have CFI/EFI box Panthers with the in-tank fuel pumps. I started by purchasing a stock pump (Spectra) from RockAuto. As we know, the stock pumps are physically larger than the aftermarket Mustang pumps (mine is a Holley 190lph). In order to get them to fit correctly inside the rubber boot, you have to fill in the empty space with something. I used a NAPA (part#8104) radiator hose for some '80s Chysler. My inside diameter of the stock rubber boot measured 2" I.D. So I needed a 1-15/16 - 2" O.D. hose to cram into the boot. I brought the Mustang pump with me to NAPA so we could scrounge in the box of miscellaneous hoses. Luckily, it didn't take too long to find the hose I ended up using. The Mustang pump fit snuggily inside the hose and the hose fits very tightly inside the boot. After that I just needed to cut and splice the Mustang connector to the stock wires. Here are some pics below to show you what I used.







    I have yet to build the engine that this pump will feed, but this is what I did. I probably should have gotten a 255lph pump; but whatever. I am also not sure if all pumps and boots are created equal. Hopefully this helps one or two of you out there.

      I forgot to mention that before I took the stock pump apart, I traced an outline of the pump on cardboard. That way I could adjust the height (so-to-speak) according to the stock pump dimensions. And the fuel line that goes from the pump to the outlet is 5/16" fuel line.

        Also, I used a box cutter to cut the end of the rubber boot off. Then I trimmed it back accordingly with the radiator hose.

          That is how you're supposed to jack it.

            Nice! I did something similar using a NOS hanger and 255 cnt racing pump. Even if the engine is stock a 255 pump doesn't hurt a thing.

              Some replacement pumps come with a sleeve to compensate for the diameter difference. I know my stock replacement Airtex pump did. What's nice about that one is, it's reasonably priced and equates to about 189.89 or so LPH.

                Radiator hose is not something that enjoys being submerged in gasoline.

                  yeah, rad hose will get extremely gummy in gas, and all the goo that it breaks down to will get sucked through your fuel pump.

                    I ended up cutting up the old boot to actually use as a filler between the pump and the new boot. Considering the car is still running fine I think that worked fine. Todays gasoline is very hard on rubber. Especially the e10 stuff which actually dissolved my original pump's screen strainer. So needless to say be careful about this.

                      There are hoses rated for alcohol & gas. Though this would need to be fairly large so it is not common. Marine supply might be a source. This type of rubber is expensive but you would only need a foot.

                        Good to know. Thankfully, my project has been delayed for a couple years. Otherwise, I would have learned this the hard way.

                          Mine doesn't have anything to take up the space. I sliced a hole through each side of the boot and used a hose clamp to keep the pump where it needs to be. Been in there for years now, so I guess it works.

                            Someone should still sticky this thread so that it's at least easier to find and the idea is documented. I just got my Walbro 255, being that there is about 1/4" of gap all around the pump, I'm currently finding a solution to the space and pump sock problem.

                            I ordered an Airtex 190 and plan to use the rubber spacer that is supplied.

                              So I went to NAPA a week ago and got 1.5" ID fuel filler hose. It matches the ID and OD of the radiator hose that I originally got. Tore up the fuel pump filter whilst removing it. I bent the tabs back into place, but it doesn't snap in like it did the first time. I will see if I can get a replacement filter element and then re-install the pump.
