Accufab adjustable fuel pressure regulator

[BigKriss]

I am trying to install this at the moment. It goes on the stock location of the old fuel pressure regulator. I had to get some longer fuel hose. I am going to hook up a fuel pressure gauge soon.

It was leaking though. I ran the car and petrol was coming out. A second time I put some plumbers tape on the fitting thread. It was leaking still but not as much as before. I will try tomorrow and look to install a new fuel pump too.

Looks nally dude

You have to nail the bend in the hose and its length of course- Are you going to get an L fitting for the bottom of the FPR?

I will try. I haven't found one yet though. The thread is M14x1.5. This is the manufacturers fitting www.napaonline.com/Catalog/CatalogItemDetail.aspx/Fuel-Line-Repair-Kit/_/R-NDP7304928_0412991622

The hose will kink if I currently make it shorter.

Hi ya Big K, can u tell me about this device - adjustable fuel pressure regulator. I just got me a 535ia exec and im curious about the adjustable part of the system. what does it do?

[BigKriss]

Hi Matt. It adjusts the fuel pressure to the fuel injectors. I don't know how useful it will be overall but I want to use it in tuning when I turbocharge the car. A gauge will need to go on to see what fuel pressure its running.

p.s think I just bought another e34 that makes 3, oh ****

Looks good Kris. Thanks for posting. I see you got an additional temperature sensor there.

I installed this today. You can see the video here. http://youtu.be/kq2chxCZZts

I purchased some fittings to make it work. M14x1.5 to -4AN, then a -4AN 90 degree bend, then a -4AN 180 degree barb that goes to the return line. The M14x1.5 fitting was leaking so I put a fuel injector o-ring in there that I cut out a bit to make smaller. It stopped leaking after that. I also added some loctite 567 to these threads.

I then adjusted the fuel pressure to 42 psi on the gauge with the vacuum hose off and on it goes to around 37 psi.

Looks good.
