How does a fuel pressure regulator work? Adjusting a fuel pressure regulator. 4age regulator.

This video is all about fuel pressure regulators. How they work, how the vacume hose changes the pressure and why it does. Finally it explains how to adjust and calibrate an adjustable fuel pressure regulator. All this was done in an open engine bay of a Lotus 7 with a 4age Blacktop 20v in it. Enjoy. Rex from Inglewood New Zealand. Check out two Facebook groups that i lead: 4age New Zealand and Lotus 7 New Zealand.

So at what minimum pressure did u find a decent power and have u achieved better fuel economy?

What causes a misfire in a 4aje

[@SimonTrent8000]

You should be running an afr gauge. You might find your low to mid is because your running to rich. Running a silvertop 20v with a blacktop ecu when ever i floored it afr was pegged at 10.0. Got a regulator and dropped the wide open pressure down to 36 psi works much better and now im getting between 11.2 and 12.7 now threw out the rpm range.

Why a fuel going in to oil

[@planesofpaper]

If your injectors leak when the vehicle is not running then the fuel leaks past the piston rings over night.
