Mk1 - F4R, Fuel pressure regulator??

[midge]

Going to be deoing this conversion soon, ive noticed on the ph1 172 fuel rail there is no pressure regulator and just one fuel line going to it, where as on my mk1 there is 2 lines and a pressure regulator, how do i over come this when doing the conversion?

 

[sideways danny]

you need a ph1 rail that uses 2 lines and a regulator in the rail

ph1 172 have two lines and fuel pressure reg ph2's that have it built into the tank

The ph1 outside my house has 1 hose in! It is the twin lambda loom to.
Does this mean i will need an earlier loom aswell?

you have a very late ph1 then. seen a few like that, but the majority are 2 fuel lines. could convert the mk1 to single fuel line (beanie has done it) if you can be bothered. standalone FTW

phase 1 bits ftw, i have a spare fuel rail with injectors, phase 1 so 2 connections for the lines ;-)

Stand alone is expensive! Do you think i can use the loom on the car? it was cable tb.

i would have thought you would be able to. i thought the second lambda is just for the dash warning but i honestly dont know

The loom ive got on at the moment is a twin lambda loom. The loom I originally used was a twin too with the wiring chopped off, so id guess my ECU is a twin lambda one too. All runs fine.

it is just for a warning light. wont effect running at all. most important bit is having an ecu for the same fuel line setup that you have really

pah, even Laine has got his wallet out for a standalone, and he doesn't even own a phone with a camera on it LOL

not to steal thread but my 2001 ph1 has single fuel inlet rail with pressure regulator in fuel tank
