The previous owner of my car installed an adjustable fuel pressure regulator.

Why would he have done this?

How do I go about adjusting it correctly? I have an air/fuel ratio gauge, but that isn't much help.

Thanks in advance

 

He may of had a differnt turbo set up or thought he ran lean at some point. You want to just have it set to 4bar (~60psi). Need to know what kind you have to help you set it if its not already there.

 

i have a 034 motorsports adjustable fuel presure regulator and i have it because i noticed that one day the bowl that the regultor sits in was filling with fuel and 034 had a sale on the adjustable ones which made it 10 dollars more then the factory replacement one since my only opition was the dealer. what kind do you have does it have a name on it or a picture can help us help you

 

It's an audi brand. Has the rings on it. The adjustments are made with an allen wrench.

Here's a close up of it.

 

do you have a fuel pressure gauge under the hood too?

 

not that I know of. Can it be done without one?

 

not that i know of

 

Put it this way, its like messing with boost w/o a boost gauge. Not something you want to do.

 

no gauge = no good, I would fit a standard one or have it tuned

 

All he needs to do is get a gauge from ecs for like $30-40 and cut the fuel line and slide in the gauge. All he has to do is pull the fuel pump fuse and let the car run till its stalls out.
