Fuel rail

[Jay325]

Which end of the rail is inlet and outlet?......In other words is the fuel pressure reg end inlet or outlet of the rail?

[yberther]

I'd love to know.

[matt]

Pressure regulator is the outlet.

[nando]

Pressure regulator is the outlet.

yep!

the fuel goes into the rail, and the excess pressure is bled out the regulator - which is also under vaccum, so the pressure differential between the injectors and the intake remains the same as load increases on the engine.

[yberther]

inlet is firewall side? outlet is the other?

[Aptyp]

You have it backwards. The inlet in on the forward side and the FPR/Outlet is on the back end.
