Eric...forgive me for my Nubish question, but what are the signs that the fuel pump is failing. I would hate to find out the hard way when the engine blows. Also, everyone says the pump is noisy, however, I never heard my pump!

I'm being tuned next month and the tuner is recommending upgrading the pump. It's no big deal, but I wonder if a fuel pressure guage should be put in first to see if there is a need for the pump right now with my basic bolt on mods. I have read that the OEM pump is good till about 350 whp. I'm nowhere near there and don't plan to be in the near term.

The stock fuel pump is only good until about 340 - 350whp. I think turbo mag made a mistake if they printed that.

Turbotrix
P.S. rory was inside his gas tank helping me so i def couldnt of done it wrong.

I got the PE pump also and I'm glad I did. At first I was kicking myself for paying that much for a fuel pump but I knew it was going to be better quality than the walbro. Eric, why do you suggest re-using the stock filter? The PE comes with a whole new filter assembly attached.

just like all mechanical things some times **** fails....... it part of Physics.......... Walbro is a very good pump.. i have run it on two different turbo'd cars and one being a dsm.... **** can happen to every company unless ever one is QA and guarenteed to not fail which is impossible.... i would just stay with walbro................

My car is slightly modified and I was all but ready to pick up the Walboro 255 until I saw this thread. Modified at power levels under 300whp with mild boost increases how much of a risk is there running the stock pump? Running a car on a dyno unventilated for multiple pulls where the car will begin to richen up might be the cause for any failures but how applicable is this as far as real world goes. Ive heard different things from a number of individuals whos opinions I respect which makes things tougher. I might just take it to war this summer on the stock pump prob putting down no more then 250whp at slightly elevated boost levels and hope if it does fail it fails on Mitsus watch, because if a stock pump causes the engine to go you should be covered, but If theres any evidence of tampering through the use of an aftermarket pump, there may be probs. Still undecided but the weathers starting to warm... maybe a fuel pressure gauge that I should have anyway will tide me over.

**** another problem. Looks like the Walbro blow the relay. Now no pump will prime.
Yes reuse the stock filter or Tea bag. Alot of the WRXers were having problems with the stocks that came with the walbro kit. So just incase you do not want fuel starvation.

A common upgrade on DSM's is rewiring the fuel pump. The stock wiring drops a lot of voltage. You can even here a loud pump like the walbro tone change up and down with the turn signal. I don't know if there is a similar problem with the EVO's, but it could be why you blew the relay. The pump was trying to draw too much current. You'd think you'd blow a fuse before the relay though...
