Shim a Fuel Regulator
 

has anyone ever shimmed a fuel regulator on a 6.0

You can do it with a .177 BB under the spring in the housing. Some have "streched" the spring for the same affect.

im a rookie with the whole fuel regulator if you dont mind is it possible to explain where its located on the truck were to get the part and etc thank you for your time

and just what shimming it does for you. better performance? help egts? or just what?

There is a pressure relief valve on the side of the upper fuel filter assembly. When fuel PSI exceeds 60+PSI the valve is pushed open to allow fuel to return to the tank. I'd have to find a picture of it to show you exactly where it is on the assembly.

I think the thought is that this would allow more fuel to go to the heads versus going to the tank.

Not the best idea from what ive heard, the Orings will start to fail.

You are correct!

Shimming the fitting with a 3/16 spacer behind the spring in the fuel regulator. This is located on the right hand side of the fuel filter. You will see a 3/4 brass nut there. The spring is inside there. Shimming will raise the fuel pressure and often give you a worthwhile increase in power and no one that I can recall has reported higher fuel consumption.

You can get a updated spring from gillette diesel. It is a little stronger than the original

I typically give the springs a little stretch, to get the fuel pressure up to INTERNATIONAL specs, not the Ford spec, which, in my opinion, is a little low.
