Does anyone even know where the fuel pressure regulator is on a 04 3.8 v6 mustang??? Please and thaaaank you

 

They do not have one, your car uses a return less fuel system. There is a sensor that the eec relies on to adjust the fuel pressure.

 

Lol tht would explain why I couldn't find it. But ok I know where that is. Thanks

 

Hey would you put an adjustable fuel pressure reg in the system or would the tune take care of it well enough?

 

To be honest I am not the person to give you a qualified answer as I have not ever played with a returnless system. It would be an easy deal to do, just get the parts off of a sn95 3.8 car. You can also get the replacement parts new, not sure on the fuel rail though, that should be available in a wreckers.
The parts should work from any 1994/98 3.8 mustang. You then would need to get an adjustable fpr.

 

Are you sure it doesn't have a pressure reg in the tank? Most return-less systems do.

 

I've been checking it out I believe it does or at least a pressure relief valve tht I'm pretty sure does the same thing

 

Converting from a returnless to a return style might be a good idea unless you wanna depend on a bigger fuel pump and probably a boost a pump. Fuel system solutions for a 03-04 cobra might be a good place to look whether you stay returnless or go return style

 

Yea I have a Deatchwerks lph 340 and I believe as long as I stay under say 450 (which is the plan anyway) the returnless should be fine. Pulling from a Cobra system is a really good idea tho I'll def check tht out. Do you know about f.p.regs for returnless? And I'll have to look into boost pumps.
