Anyone have their fuel pressure regulator mounted to their fuel rail. Was going to buy the fitting to mount it on mine. Good or Bad idea

I have done it with success on a previous set up on my car. Eventually moved it to the firewall for clearance reasons.

If you have a big mechanical fuel pump move to firewall at minimum distance.
Top of the tank is best.
Big pulses are minimized with distance.

^^^^X2^^^^ Illegal on the firewall with good reason. Mine is on the end of the rail but has a brace down to the motor plate.

I mounted mine to the fuel rail. But I'm using a small OEM regulator off of Nissan or Toyota or something. I wanted compactness and since I run an aftermarket EFI, as long as it has a one-to-one reference Port, it really doesn't matter. The only thing to note is that my pump will overpower the regulator pretty easily on the street so I use the EFI to drop the voltage to the pump. Which is a good idea anyway, once you start getting up there hp-wise, at least on a street car, there's no reason to circulate that much fuel all the time. The only thing I would do differently next time is to stage two pumps as opposed to cutting voltage to one big pump.

The firewall isnt legal unless the rule changed

Must be mounted 6" forward of the bell housing / flywheel area? On my car ( turbo 4 ) it is further then 6". I race at a very strict NHRA track all the time and have had it there for years.

However, yes for the OP the firewall would not work. I didn't really notice his car type until I saw your reply.
