fuel pressure

A guy that used to work for the ford dealer and on 6.0s said if u take the fuel pressure regulator spring out and stretch it about a quarter inch that will increase hp a good bit. He said it was good for the injectors also by not letting them starve for fuel. Is there any truth to this. He said he done a truck with just the head gaskets done and he said it outrun a 6.0 that had a 75hp tune, he didnt say what kind of tuner it had. He also said that this is what the ford engineer said to do for repeated failing injectors. Any thoughts?

My advice would be not to mess with the regulator spring unless you have a way to check fuel pressure.

Do a search for "BB mod".

Pretty simple really, you take a BB out of your BB gun and shim the spring with it. The hardest part about this whole mod is getting to the spring. Good luck with the mod. BTW, I agree with the above response, I wouldn't do any fuel mods unless you know what your fuel pressure is.

My apologies, PowerstrockedSC. To my surprise, there is very little in the 6.0 forums on this site about the BB mod.

Countryboy07 hit the nail on the head. You pull the four screws that hold the regulator cover to the side of the fuel filter house. When the cover comes loose, be careful not to lose the brass cup, the spring, or the plastic air bleed fitting. Place a BB in the brass cup and button everything back up again. This adds about 10 - 12 psi of pressure.

So long as your pressures don't drop more than a few psi at WOT, your pump is still supplying the necessary flow at the higher pressure. If your pressures fall quite a bit at WOT after the mod, your pump is tired.

PS:
I have a feeling that your "guy who used to work for the ford dealer" is full of BS when he claims that a Ford engineer instructed him to stretch the regulator spring to eliminate repeated injector failings.

If you lose any of these pieces, your going to have a little bit more time involved I droped the spring on my dads truck and couldn't find it for the life of me. I just about gave up and was going to order a new one but then out of nowhere, I found it. What should have taken me about 30 min or so, took me 2hrs

I would save your money and do a fuel system. the theory is there but I dont trust all that.

I hold 60psi at wot. I deleted the bowl up top and just feed the heads with their own lines coming off a Y block. no return back to the tank.
