I Just upgrade my in tank pump on my R33 GTR.. When I was doing it I noticed there is some kind of regulator in line inside the tank? Should I remove this regulator or is it fine to stay? I am currently running the standard external FPR if that makes any difference. That said I may need an upgrade!

Thank you

I see.. Someone else told me it was a pulse dampner? I thought that was more likely the bit on the OEM pump itself?

So in fact I could take the one way valve out of the Bosch pump if I leave this inline one there?? I presume that might give a little extra flow from the pump? Or is it not worth it?? I actually think the pump is not the issue now but preparing myself with all the options just incase!

Thank you for your answers

Why on earth would you open the fuel pump? The thing in the fuel tank looks identical to the unit on the return fuel line in the engine bay and if so, it is a dampner. My old skyline ran without one in the fuel tank and it ran just fine. Ive got one now because I'm using a GTR pump. Didn't make any difference. If its there, leave it there. The fuel pump will pump the fuel, your regulator will hold the pressure. Its a simple system. So long your lines aren't run dry every time you turn the car off, you'll be fine starting it up.

Not sure exactly what we're talking about, but isn't it a check valve that keeps fuel pressurized so the instant the engine is cranked there is fuel versus not having it and having to crank for abit longer?

    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
