Great write up with pictures and visual descriptions MM...

I've been dealing with a mysterious problem that I've been trying to diagnose for a while now. I've narrowed it down to the fuel pump and after reading up on this thread I wonder if this is the problem I'm experiencing. Symptoms are after long highway drive, I seemingly lose throttle and sometimes the car won't even start. But after an hour or more of sitting, it will fire up and run like normal until the next time it decides to fail on me again (no CEL codes).

I was planning on ordering a 09 pump, but seems like this may be the better route (and cheaper). Though I was curious, being that I'm not using any type of force induction, will the added fuel flow increase pressure in the fuel rails to a point where I'll be running in a rich state or is the FPR able to compensate for the added pressure?

Thanks in advance!

great thread. I knew Jeff had something up his sleeve

once there's consensus on the correct part, I'll buy it, and see if it fixes my lean 6k+ rpm afrs.

^Do you know the secret model number of said pump?

This is the best I've found and I'm 99% sure it's the right pump and it's from a reputable site: http://www.maperformance.com/walbro-...o-wrx-sti.html

I have yet to verify this, though.

you might be on the right track here wafer. But Jeff has yet to give more info.

Geez Todd, I asked multiple times and no one is providing the secret squrriel part number. What the hell am I supposed to do? I Google

In the post you quoted me on I even asked Ray directly if he knew the part number. No responce- so yes, I did ask.

Aside from that, I am a Walbro dealer but we all know that Walbro pumps suck, don't we?

Brettus didn't you read this?
It should remind you of the word "test"indeed, doesn't it sound good? i know we aren't used to tests but seriously i wouldn't like a crappy pump to stop pushing fuel after a replacement because the seller didn't sell me the best item available

Let's be patient, you (and i) all lived with the stock pump for a while so why should you be all in a hurry? I trust Charles, Jeff, Todd and Erick.. just giv'em the right time!
In the end they never let us down with products and tests, always backing up their opinions in a good way. I'm sure that the wait will be worth it!

Well since Todd (an employee of BHR) told me to check with you on the PN and the price, what is it, Ray? Or was Todd just blowing smoke? I'm really curious now.

No trappings, I just didn't like how Todd was trying to call me out when I thought I already asked you?

I just thought the comment was uncalled for and rude considering I already asked multiple times. That's all

Since women apparently share the same firmware version, could your wife tell my mother that upgrading to another LSD is a good idea?

Or i will have to run naked again, as said in that for sale thread
