To connect the FPR pipe to the Brake Servo requires a new brake servo one way valve with a small take off. Some people have got these out of scrappies but there is a part number on the original thread somewhere - its about £16 and mine broke as the FPR pipe was too tight.
Ive been running the FPR to atmosphere, but this causes very rich idle and looses low rpm torque but is great at high RPM (4bar always).
Running the FPR blocked on the fuel rail causes the car to run very lean (3bar always?).
Running the FPR to the intake hose makes the car run ok but you can feel it start to really lean out above 4500rpm with presumably not enough WOT fuel pressure! (Probably about 3-3.6bar variable at a guess)
Im going to make an adapter for the fuel return pipe at the top of the inlet manifold now as this can leak air on mine 🙁 Ill 'hard wire' this with a 2-way for the FPR also. Saves fiddling with the servo hose!!
