Default PE fuel pump dies - POS - need info on supra pump

Went to start up my car to go get some c16 gas this afternoon - it was dead - no fuel prssure

The POS bomb maker PE pump was dead - -

And that dude with the thread on the loose terminals was right - the stock pump connections are tight as can be - but the pe pump connector was loose and shaking about

I can't believe these things only last a few months !

Now I am screwed and cant go racing becuase I put the stock fuel pump back in and it cant hold enough pressure on top to make the right power

I need a supra pump - anyone know a vendor who has one in stock ????

Thanks !

That $ucks. Luckily it didn`t decide to die in the mid of the 1/4 mile. That would have been messy.

Good luck.

Somone posted the supra pump number a while ago. It was # 23221-46110 just ask goto a toyota dealer for it. This number was for a last gen impreza, not sure if it will fit a wrx. Hope this helps.

Al, I am the dude that posted the problem with the PE pumps.

I bet its not blown. To test it hook wires directly from the pump to your battery or power supply... Caution! Dont run the pump for more than a few secs. The fuel cools and lubricates the pump...

If it works redo the connectors and put it back in. MY car did the exact same thing on the F*&^ Highway. I had to have a friend tow me home. Once I had solid connections I had no issues. The PE pump might have the connector problem BUT... It fits and takes the stock pick up tube.. The supra pumps input is at an angle so you will run out of fuel before the light comes on..

Did you do anything about the stock FPR and rails?

The Supra pump will take the stock pickup as well... You do have to modify the tube on the pump housing, but with a little work the supra pump will fit like a charm.

We take a dremal tool to the stock sock, just grind off just a little of the lip that keeps the stock sock from fitting the supra pump. Its a simple 2 minute process, and then you have the best of both worlds. Lots of fuel flow (255l/h) and limited surge (just like stock).

My next mod is to get a surge tank anyway though, because id like to have a little better ability to run with low fuel at the track.

the STI surge tank, and the supra pump might be the way to go.

Nate. Is the input tube to the pump at an angle??? I thought that was the issue. Does the screen rest on the bottom of the tank? I too would like a surge tank as I road race. I am thinking of ideas. I saw a good FAQ on dsm.org about a total system upgrade. Good ideas. I want to ditch those sending unit fittings.

same happend to me AL!, remember? We blamed the pcikup, as we fitted the pe pickup and sometime we were getting fuel surge, and it lasted only in 2 months, we got the new one, I did not put the PE conector, we fitted it now to a sti surge tank (just a plastic fancy and expensive device) and no troubles untill the moment`, next week will try to tight those conectors better...

ADAM is the guy to talk, seriour power leads to the BIG denso fuel pump, wich I think is something aorund 500$ and it`s good for like 800-1000HP.. just enough flow.. eh!

See ya! I hope you are doing well...

The parts on the pump sits in almost the exact same place as on the stock pump. The issue is that the supra sock comes off at a dead 90 degree angle from the supra pump. This leaves it out of the fuel in an under 1/4 to 1/8th of a tank situation.

When you try to push the stock sock onto the supra pump, if you look close enough you'll notice that the plastic lip on the stock sock keeps it from pushing all the way on.

Trim this lip just a little bit and you have "stock like" fuel pickup, with the larger pump.

You will also have to trim just a little bit of the factory feed tube that the pump mounts to in order to get everthing to fit back nice a tight. But thats pretty easy.

I still think i want a surge tank because i DO not want to ever run out of fuel under boost.

Al,
The supra pump has studs that the wires mount to... Pick up a few nice Male/Femal connectors and cut the stock plug off the pump assmebly.

Use some extra wire and the Male Female connectors to lengthen the stock power wires, then get the right nuts and connectors for the studs on the pump.

Pretty easy stuff... We did it on Max's car in less than an hour start to finish.

i run the surpa pump... don't bother with the toyota dealer unless you are going to try to get on in the morning. Usually they don't keep these in stock though. You might want to talk to adam, he usually has a few around.

Check out the DSM club deal on the pump at partznet.com. I dont think your going to find it for less than that.

Well I love PE stuff

Also seriously thinking of the supra pump

If I get the supra pump then I also have to re-map all my fuel enrichments to incorporate the increased flow - which may not be a bad thing (the extra capacity)

Ah decisions decisions

I have been using a Bosch Motorsport pump designed for an RS4. It supplies 248 ltr / hr and mounts like it was designed for the WRX. Mounted in a block of fuel cell foam, it is not until the needle touches the "E" on the guage that any surge is experienced on the track. Cost was only ~AU$400 installed. I highly recommend it. Even with extreme modifications it does the business. It doesn't come with ricer stickers for the rear doors though!

Do you have a Bosch part number?
It's probably even beefier than the pump the S4 gets here...even the S4's pump should be better than what we have.

We get no RS4

god / Dan:

I remember you a few years back from the H/A board (I sold my Integra Type R b/c I couldn't afford to keep replacing stolen parts). Do you still do H/A work, or have you made a complete switch to Subarus?

The supra pump flows a lot of fuel 290 lph @43psi @14v, you might need an adjustable fuel pressure regulator(not the b&m crap) because it will over-run the stock one. You'll be wasting a lot of fuel and will wonder why the car runs rich/slow.

shabby...not true on subaru's..their stock fpr's do a MUCH better job at coping with increased flow than the DSM's units do..it is one of those rare examples where Subaru has surpassed Mitsu (cough)



Granted, at Al, etc. stage of mods, a proper adjustable fpr would do a worlf of good, but only if the ecu is tuned to see it.
