Thread: Walbro cause bad injector(s)?

Not to long ago I kept blowing 370s and didn't know why. Trouble shot and swapped out my 255 walbro back to the stock B14 Fuel pump and the problem went away. Why were the injectors dieing? Bad walbro 255? Cause of the stock FPR? I tried 2-3 stock FPRs and kept happening till I put back the stock fuel pump.

B14 JWT tuned for 3 bar, stock B14 MAF
370s
B14 FPR
Walbro

Dude, mine is doing the same thing, i changed mine to a 255 & i went through one injector already.

How are they going bad?

maybe the strain of a ton of fuel pressure on almost 20 year old parts are killing them. someone figured out the fuel pressure of a walbro on a stock regulator. ill try to find it

Im sure running them at higher pressure doesnt help and yes with a stock regulator they will run at slightly higher pressure than with a stock pump. But I doubt the Walbro is the direct cause of killing injectors. They are old man.

Ive ran them with no issues, ive done 15+ det's/de+t's and so on that ran them with a walbro and no issues either. I think out of all of them a friend had one injector die on him and his car has been boosted for 4+ years.

Well for me you can hear that spcific cylinder not firing cause it is not getting fuel. Swapped that injector to a different spot and that spot that I switch it to will not fire either.

Maybe I was having crap luck with my injectors+walbro cause mine killed 3 and once I went back to stock pump never happened again.

been running a walbro and msd injectors for 5 years no issue, never replaced the injectors or the fuel pump....sounds like bad luck

No issues man. Maybe you need a new set of injectors

370s are ran at 4 bar all the time. The higher pressure isn't killing them.
