What year of truck do you have?

I have a regulator off my 96. It should fit any OBS trucks and I will sell it for way less than that.

It would help to know what truck u need it for!

My 96 needs 24psi of pressure to run and 95psi at full boost (if u go by the guys selling the stuff) anyway u can buy a regulator (aftermarket) from most part stores or Summit, or any performance shop.

I paid $130 for mine it goes from 15psi to 100psi and is boost regulated(that means when the boost goes up so does my fuel pressure).

Hope this helps!

*If* you are planning to do a custom fuel system / regulated return, here is what you need.

Fuel pressure should be no more than 64psi steady, idle to wot, unless you want to place additional stress on the pump.

If you're having problems with the stock fuel bowl / regulator setup, now is the perfect time to do something about it. If you're willing to gather the parts and do the work yourself, you can do a custom fuel system with reg return for the $380 they want for the regulator you found.

I have a 95 7.3L turbo by the way...

You say 64 psi "steady" My needle bounces back and forth every stroke...

The 94-97 7.3 engine uses a piston (or plunger) stile pump, just like the rockers the piston goes up and down as the cam goes round! The pump has a low side and a high side, it pumps both ways up and down this causes a slite drop in pressure(your gage is too sensitive so it seems to jump)!
Your pressure seems fine to me. I would check the screen I listed above because that is what caused my truck to fall off on top end and caused it to shutter when lugging. You might also check the HPOP pressure, if the HPOP
(High Pressure Oil Pump) is not providing enough pressure it will cayse the same problems.

By the way the 7.3 in these years used a single shot (From factory) injector they only need 24psi to start and idle, but i set mine at 50 psi at idle with my size injectors! It is an Aeromotive A1000 pump and dual inlet regulator, as Locomoton said he has listed a site for you. It was cheaper to replace my factory system than to rebuild it! But I would check the cheaper stuff out first like the screen! GOOD LUCK!
