I just need to know if the fuel return off the FPR is pressurized or not, and if it is roughly how much pressure is going through it?

Thanks!

 

I don't think it is, but I'm not 100% sure so wait til someone who does know 100% to chime in.

 

If you think about it its basicly just as pressurized as the in line to the rail. The return line comes right off of it, and the injectors just grab fuel as it goes by inthe fuel rail...

So you're saying you're not 100% sure either?

 

yeah im not 100 % shure, but how could it not be? It would at least need enough pressure to keep fuel from coming back into the return line from the tank, and it needs enough pressure to "push" the fuel back into the tank.

 

There is a small amount of pressue because of the fuel pressure regulator. How much? Im not quite shure.
