if its and R33, the fuel reg is on the fuel rail, i think, and i can't see the photo properly, if that is a photo taken in the Driver side wheel arch wall, then its a damper and an drain valve. The r33 has it to stop pulsing of the fuel flow and antydrain back to the tank.

Probably not. As your r32 26 is, as is his, with a fuel pressure regulator mounted on the most foreward part of the fuel rail, near the top radiator hose.

Is there only 2 hoses going to the unit, both fuel? then it'll be as wogsrus says.

I can find the fuel damper in this location in my r34 diagrams, but i have no r33.. but thats what it is on an r34 anyways.

just checked an r33 manual. definate fuel damper.

i must be bored..

Awesome sounds good to me :) I'm putting in a dual entry rail, braided lines, aeromotive reg, 044 etc. Do I still need one of these in the line or is it not really required, just one of those extra happy things factory cars have....?

BTW it's not the fuel reg, fuel reg is located on the end of the fuel rail :P

lol just been reading through the manual I have, forgot all about it, it is actually quite good :sorcerer:

Most of the set-up's i've seen don't have one installed, well not anywhere visible anyway :laugh:

Also you wouldn't happen to have part numbers for the o-rings and insulators for the injectors and also the insulators for the fuel rail to block....

By strange coincidence, I just had my injectors serviced today, clean / test / pintle caps / insulators / o'rings. Have also had to purchase two replacement injectors for the two leaking from the housing,.. bstrd.

Didn't get a price on them but 4 injectors done and 2 just tested were $100. I know nissan are about 15 for each o'ring and probably worse for the insulators. Just get them serviced, be better in the long run anyway.

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
