    Get a GENUINE fuelpump, they are cheaper, well used to be and better probably. NEVER NEVER EVER EVER mention second hand fuel pump around me.
    1. suck ya fuel out
    2. jack it up
    3. onplug pump
    4. make sure you know where the top is, mark it if you need to
    5. get a drain tin, large, undo the bottom fuel pump bolts a bit and let it drain until it stops
    6. remove bolts and carefully manoeuver the pump assembly out of tank, dd i say carefully?.
    7. carefully disabssemble and replace pump making sure the thing is put on correctly. DO NOT BENCH TEST!!!
    8. Carefully manouvere the pump assembly back in, did i say carefully?? very carefully. dont forget new cork gasket
    9. hold on place and put bolts in tighening them up gradually in sequence
    10. plug it all back up
    11. lower vehicle
    12. FILL WITH FUEL REMOVED
    13. start engine.

    you might wanna change the fuel filter while your under there.

    i know im stating the obvious here but dont go to super cheap and buy one of their cheapo 'fuel miser' pumps or whatever they are. it will die a week after its out of warranty.

    surely a good genuine bosch pump at a decent price cant be too hard to find

    A couple more hints/tips:

    Use a thread sealer on the bolts - they pass through into the tank. Not a silicon sealer. Use Loctite 242 or similar on clean and dry threads.

    Support the car under the body and let the rear axle hang. That will give a little more space to manouevre the pump assembly out.

    Note and match the orientation of the strainer "sock" when removing and fitting on the end of the pump pick up.

    While you're at it, check the breather hoses to the filler pipe and on top of the tank and replace the perished ones (usually all of them).

    And as everyone has said, buy a quality pump.............unless you want to do all this again in a year's time.

    new factory pumps are ac delco now and come with new gasket and strainer..DONT BUY SECONDHAND from wreckers...they are cheap short term .... but you will be doing it twice .......... Be careful with internal rubber return line when removing unit from tank flange as it breaks easy. When refilling with fresh fuel after job it takes quite a bit of fuel to fill up swirl pot in tank so the new pump primes and picks it up....in my case 20 litres.
    This is my vr that I rebuilt ....CLICK HERE to see my vr on Cardomain ......if you want to check it out......Anyway make sure you rubbish a ford daily ....I am a 4DH8RZ Club lifetime member .................new members joining everyday

    I had to change mine on a long weekend so I used a spar eone I had at home. The cork gasket I just used stag jointing paste on an old gasket and put a bit on the bolts as well. It didn't leak at all.

    It's also better to try and syphon your tank out as if you let it run out the hole in the tank it can disolve all the tar that's painted on the tank under the silver foil to stop the straps wearing a hole in the tank.

    Last new fuel pump I bough twas genuine, it was DELPHI and I got the pupm, strainer and gasket from a local dealership for about $100.00, another dealer wanted $170.00
