Hi all,
My XC was fitted with a slightly modified efi engine some years ago and the I have two inline fuel pumps between the fuel tank and the fuel rail. The guy that put the system together has fitted a fuel pressure regulator in the fuel line after the front pump and before the fuel rail. There's also the standard regulator bolted on to the exit line of fuel rail. I'm spinning my wheels doing upgrades on everything for the first time and feeling my way. I have a new fuel pump regulator (with Gauge) ready to be connected.
Question is, do I really need another fuel pump regulator down in the line before the fuel rail? Seems like overkill and complicated.
Anybody there with suggestions?
