Low Fuel Pressure

[Fadie]

I have been told i have low fuel pressure im my r33 gtst. i have recently put on a Bosch 044 pump.

Has anyone else had a similiar issue, or could it simply be a faulty fuel pressure regulator??

it will more than likely be the fuel pressure reg, unless the pump just happened to be faulty from new.

first, what pressure do you have? Where are you measuring it from exactly?

Have you tried replacing the fuel filter in case it's blocked?

How did you mount the pump? Could there be some blockage at that end?

After checking everywhere for blockages I would suspect the pump before the reg first personally.

agreed, I don't think I've ever encountered a faulty standard fuel pressure reg. I've seen plenty of faulty bosch pumps though, and just as many fauly installations. and the odd aftermarket fuel reg failure (cough, malpassi) happens too.

if the pump is the most recent thing you've changes that's what I'd be looking at.
