Your regulator might be shot (or you've run the Walbro dry too many times and it damaged the rotors of the pump).
Have you actually monitored the fuel pressure? Does it always hold stead right after you turn the car off?

 

Have never run it dry .


No gauge so no can do .
It seemed to be related to the low fuel level . It's never happened with a full tank .

 

I just read 16 pages of people asking for the walbro pump part number... I'm gonna ask the same thing.

What's the part number of the walbro pump so I can order one?

 

FP gauge seems to be pretty rare for FI guys, why is that? To me it seems like a pretty necessary gauge for safe FI. Maybe i'm missing something...

 

I am, apparently, one of the few people that agrees with you.
After losing a motor to low fuel pressure, I not only have a gauge, but the fuel pressure is directly tied to the turbo wastegate. If the pressure drops below 48 PSI, it dumps all of the boost.

 

years of reading everything i can find about adding FI to a car keeps leading me back to FP being critical but overlooked.

I've read of people tying FP readings to kill switches and that just sounded unsafe (and i've only read about it being used in race applications), I like the idea of FP tied to the wastegate. That little nugget is going into my FI file.

 

at one point in time, the entire 'gauge monitoring' ordeal on this forum was to monitor 3 specific items: oil temp, oil pressure, and water temp.

Lots of people, including myself, jumped in that direction even for FI. Well, that and a boost gauge. I don't know why I did so myself. I would have gotten the fuel pressure sensor to hook up to my camp2 already, but I've stopped the car mod purchases until I figure out what's going on with my car.

I really like the idea of having the fuel pressure tied to the wastegate, is that entirely implemented with the E-01 or did you have something rigged for it?

 

All through an analog input on the e-01.

 

hobb switch ?

 

+1
Comes stock with the CRH nitrous install :p

BTW not to suck up (ok maybe a bit) ... BHR offers a very cool Fuel Line Adapter ... hooks right up to the OEM lines without having to cut in to them ....
Was thinking of upgrading my fuel pressure setup with this.

Yes, this is key.

I also have the FP gauge from Autometer with a warning function. http://www.autometer.com/cat_gaugede...id=3917&sid=75 to be exact.

This will flash and change color at a preset PSI, as well as control 3 analong oputputs to do cool stuff like what Jeff does. I have considered running one to an ignition kill switch, but so far I haven't seen it drop below 58PSI on my car. It flashes color at 55 to let me know to come off it.

 

So is the fuel pump assy no longer available? It's not on BHR's site anymore, as is the fuel line adapter.

 

WOW!!!!
I just noticed that!

I'm sooooo glad I bought my ASSY when I did, phew.

Now the adapter is back, maybe just website problems.

 

New, bigger and better things on the way.

 

well it seems like I will be in the market for new fuel pump. My car "stumbles" when driving WOT. I have looked into multiple different possabilities but now I am leaning towards the fuel pump. 120k on the car, never replaced the fuel pump, so its time anyway

 

^^ time to check fuel pressure

 

too bad thats not a simple task

 

Just when I was thinking about doing the fuel pump.. Lol. Now I must wait.

 

 

Yes i have had the problem and replaced the pump about 80000 ks ago and its failing again . I do huge K's and can sit in my car for 3 hour stretchers. WA is a big place,
Any way I didn't know what it was and I was miles from nowhere. car stopped and it just was able to be restarted and i continued. It continually worsened and would would happen more on a half or less tank. I was just turning the motor off while i was driving ,turning it back on letting it kick start. Very dangerous if I did it while I was passing
I will get the issue fixed the way you prescribed
Thanks again

 

Tease.
You better tell me in Vegas...

 

Then you know who to call ... just 'cause i was born in this crap part of the world it doesn't mean i have to miss on the good things

 

I continue to suffer from fuel starvation even after imstalling the Walbro fix so I am planning to add a 2nd fuel canister/pump assembly into the passenger side of the stock tank. The cross tank line would be disabled and the outflow lines would be 'Y'd to a single line to the fuel rail.

Has anyone tried this or have comments?

Thanks.
