hi,
how easy is it to fit an uprated fuel pump and will it cause any running problems with an apexi pfc.Will i need to have it remapped?
chris

 

Relatively easy to fit, although that said I got a fellow scooby owner (who also happens to be a vehicle mechanic) to do mine for mate's rates (thanks P1prodrive ).

1. Run car until tank is empty (although don't run out completely for obvious reasons)
2. Remove carpet, etc. from boot
3. Remove back seat and back rest
4. Extinguish cigarette
5. Unscrew fuel tank cover plate, located right hand side looking from rear of car
6. Lift out assembly containing existing pump, filter sock etc. and disconnect all fuel lines
7. Mop up excess fuel that will undoubtedly spray all over the inside of your boot
8. Swap fuel pump for uprated pump (probably Walbro 255), keeping original sock
9. Refit assembly and refit all parts
10. Cross fingers and try and restart engine

Bit of a noddy guide but that's the main points covered (IIRC )

 

as above but will probably have to disconnect the hoses before lifting out the assembly.

Shouldnt really cause problems unless it overpowers the fuel regulator so you may be running a bit richer

 

make sure you depressurise the system before taking off the hoses. Take out the electrical connector and then turn the car over til it stalls.
They also forgot to tell you to disconnect the battery after turning the car over. Might as well be careful while fuel is everywhere.
I did mine from start to finish in 1 hour, and I was going by instructions on here. Good luck.

Oh, and no you don't need it remapped, although you might get slightly more power if you do as you will be able to supply more fuel easier.

 

cheers.
sounds quite a straight forward job!!

Mapping depends on which MY of scoob it is..!

Chris, If you want pictorial Scooby Mag guide then send me your email address and I'll send them over.. Newage BTW, but essentially the same for all scoobs.

Isn't it safer to have the tank full rather than empty..?

Petrol vapour is far more dangerous..! Have you ever compared dropping a match into tin that's full of petrol v's the same tin with a teaspoon of petrol..?

***WARNING/DISCLAIMER***
DO NOT TRY THIS EXPERIMENT UNLESS UNDER FULL CONTROLLED CONDITIONS WITH ADIQUATE SAFETY MEASURES AT HAND..!

***YOU HAVE BEEN WARNED***

 

I fitted my Walbro pump in about 45 mins...... from start to finish. Been running with it for a week now and had no problems, so i shouldn't imaging you'd need it remapped

 

You will still have petrol vapour with a full tank, it will just be closer to you and any ignition source

 

im a total nitwit with anything mechanical and i fitted mine in around an hour and a half.but i'd suggest a sponge at hand to soak up the lost fuel that you'll get.i did turn the car over after removing the power to the pump but there was still one hose that did spill a lot of fuel when removed.

 

It's not the amount of petrol vapour it's the amount of oxygen present, with an empty tank there'll be a lot more hence the higher risk IMO..

With regards the spill from the disconnected hoses, I'm going to use brake pipe clamps if access will allow, along with plenty of old rags.
