    Installed Walbro 255lph fuel pump

    Ok ! I installed the fuel pump about an hour ago. The pump I used was for a 1st gen rx7.
    The install all together took me under an hour and I think I could do it even quicker next time. lol
    1. I took off the gas cap
    2. then I pulled out the seat bench cover
    3. then I took out the aluminum cover over the actual pump
    4. after that I cleaned the area around the pump, with a shop rag and some wd40
    5. then I took off the screws on the pump holder. You have to make sure you use a good screwdriver and get a good grip on the screw
    6. then before you pull the last screw, you just take a pliers and pull the two hose lines attaching to the pump inlet and outlet
    7. pull the last screw and carefully lift out the pump assembly ... (take your time)
    8. then you take another shop rag and cover the pump entrance on the tank so dirt can't get in.
    9. take the pump ass. and unplug the power wire, then pull off the rubber band bracing the pump
    10. Now you can pull the holding clamps on the black hose down and pull the pump out
    11. Install the new filter on the pump -- no need to use the old filter --- makes no sense --
    12. then install the little silver clip on the filter holder peace and install the pump back in to the brace
    13. Just make sure you reinstall everything and plug in the wire to the pump. You won't need to splice wires or change the plug as it is the same ... -- I guess 1st gen rx7's and 2nd gen protege's use the same plug .. hehe. -- yerrr--
    14. Reinstall the pump in reversal of removal (which is explained above)
    15. Install the screws but don't go crazy tightening them -- also make sure the washer is lined up properly
    16. reconect fuel hose and clean up any fuel spillage
    17. replace clamps and replace aluminum cover and screw and seat
    18. Go and put the key in the ignition and turn till dash lights up but not starting the car 2 times...
    19. then start the car and let idles ... your done,, enjoy.


    impressions of pump..
    I didn't drive the car, but the idle once the car was started was much much smoother. I was very impressed... It was basically the same result as my friends civic that we installed the fuel pump in ...

    Sorry I could not take pics because my hands were full of fuel ... hehe ok ..

    Thanks for reading ..

        poor fuel pump had a wire ripped out it's ass.
        I just opened the gas cap and left it off and on the holder on the tank lid.

        Then proceded to do what I have listed above..
        No fuel spillage at all .
        very straight forward process.

          why was your initial reason for changing the fuel pump bruce?
          getting ready for the turbo, or was your current one broken?

            hope you have an aftermarket fpr or you are going to overpower those injectors...they cannot handle a 255..thats too much fuel!

              aftermarket pump, flows at stock pressure rate until raised with a rrfpr or something similar.

              ---------------
              pigeon, yes I wanted to change the pump for 2 reasons..

              1. get ready for the turbo
              2. the stock one was in there since 95 ..... --> good enough reason

                  i learned something also, i did not know that it flows at stock pressure until the pressure was changed at the regulator

                  that makes perfect sense tho

                        I am not sure yet .. I know the idle is about 5X smoother. The car seems a bit quicker than before to ... Not to mention it feals like it revs smoother.
                        But this is just what I noticed with the car. It could be just a different temperature of the day or something that causes the difference..

                        btw. the pump I used is for the 1st gen RX-7 ...

                        the plug was a direct fit.
