Guys,
I bought a 3 bar fuel pressure reg and going to fit it soon. Was looking at the car and it appears that there are 2 regulators on the car (One at either end of the fuel rail. Whihc one is it that I need to replace. Also, the regulator that I got has just a push fit hose connector where the incoming fuel hose connects to. On my exisitn regulator, the hose has a nut and flange that seals it on. Do I just cut the hose and jubilee it on?

Cheers
Sandy
 
THe 'regulator' at the front of the fuel rail is the damper which basically dampens out the pressure pulses within the fuel in the fuel rail due to the injectors.

It's a while since I fitted my 3 bar FPR so can't remember the process in detail without looking at my car, but I don't recall having to cut anything. THe whole job only took a few minutes so I guess a jubilee clip is probably what you have to undo or just the nuts.
 
Early cars have a push on and clamp fitting, later ones have a threaded connector. Some people cut and clamp, others don't want to chop up their original fuel line and try to find another solution.
 
Have you got the chips to match the FPR?

If you try & re-use the standard hose you'll find it has a fairly thick cover you'll need to deal with. I took my hose to pirtek - they took the bulkhead fitting off & stuck it onto a new fuel hose that is jubilee clipped at the FPR end. The clamp doesn't need to hold a high pressure.
 
I am going to order promax chips next week along with a tial 38mm wastegate and boost controller.
So if I just cut off the old end, will it fit on or is it too thick?

 
I removed the screw on fitting, a diagonal cut along the crimped flange. Then used a hose clip on the new FPR. As said above early cars had a hose clip later ones a proper bolt on fitting.
