Selling my Tomei fuel pump i used for the last year.

It fits as simply as the original or Walbro does, but is one of the most powerful fuel pumps you can fit as an in-tank unit.
You could use a Bosch -044 which is cheaper and flows as much as this one, but you don't need to buy any other fittings or faff about getting it installed.

I ran this at up to 550bhp no problem, but now need to move on to twin pumps, so surplus to requirements.
These cost £320 new, i'm wanting £200.

tempting....
Im also watching the twin tank installation thread so Im 50/50 at the moment

The twin pump is a load of grief Andy.
Wish i'd never started. Can't get the ****ing thing into the tank!

Bummer, Adam recently punted out a ready made setup as well.
Damn and blast.
Keep with it though wont you, the logic is all there.

AlanG

Won't be doing it again, that's for sure.
Should have stuck to where i am and kept this pump!

Back up to the top for an easy upgrade which will cover the majority of Impreza owners power goals.

Will this work on a newage ???

AlanG

Hi Alan
Yes if the tank sender/assembly unit is the same.
Having thought about that you can swap Walbro's over between classic and newage i believe, so yes should be able to do it.
Here's a pic to let you see how it sits in the cradle.

I have a walbro in now , But my car is running lean (detting) at 6500 revs, so trying for a better pump (as its maxxed every thing else out) we have tried 2 bosch pumps but they fit ok but newage ecu will not allow them to run ???? cheers Alan.

On my 2.5 with GT30R, this pump supplied enough fuel without breaking a sweat for over 500bhp no problem. It's used commonly on Skylines for around 600bhp, though they achieve that figure on lower boost than we do, so the fuel pump runs at a lower pressure, hence my limitation at around 550bhp.

What size of injectors are you using Alan as i think this may be your problem rather than the pump?

Hi Alan, car is mapped by Andy, first it maxxed the injectors (sti pinks) I got P/E 650, then it maxxed the maff Houseing I got a larger RCMS one, Now im told its running lean and needs more fuel , >> does it need more than a walbro can give ???? cheers Alan.

AlanG

I'd be surprised if the Walbro can't supply enough fuel, though i don't know what changes you have made since your 432/400 result? (i only know that because of your avatar, i don't know what boost/spec etc you have)

If the fuelling map is at its' maximum for the spec you are using just now, i'd want to find out what my FPR is set to. It could be that you could re-map the fuelling side to give you a bit more headroom if you up the fuel pressure.
Just remember, upping the fuel pressure without doing anything will make your map richer across the board, so don't alter it unless the map is being changed to suit.
It could also be you're maybe just needing a re-map cause the MAF housing was changed and is giving back different signal (voltages) to the ecu and so is running lean because of that.

Says he putting Alan off buying my pump cause i don't think he needs it!!





yet...

AlanG

Looking at the 650's i'd say you were pretty close to their maximum but you can have a bit of headroom if needed by upping the pressure.
If you look at the pic below under "6cc/bhp", you can see what sort of expected horsepower you should be able to get depending on what your FPR (fuel pressure regulator) is set to. This is only a guideline but gives you an idea what they can do.
Hope this helps.

Alan big thanks for your advise I think a trip to andy is the answer, cheers Alan,

AlanG

No problem, glad i could help.

Now then... anyone got a big build on the go that wants a drop in pump that can handle it?
