Hey all, new to the community here on SAU,

Anyway my problem is on my N/A R34 Skyline when idling my fuel pressure gauge, which is not aftermarket and sits within the tachometer (reference http://i.ebayimg.com/00/s/MTE5NVgxNjAw/z/KNAAAOSwstxVfVkh/$_75.JPG & http://s153.photobucket.com/user/demandchainguy/media/cluster1.png.html) reads 2kg/cm^2 and it idles a hair under 1,000rpm.

Would be grateful to find out what the usual reading for fuel pressure is in an N/A R34? And if so, what can I do to fix it if it is knackered.

If anyone could help in anyway, I would greatly appreciate it.

@Ben C34 I've only had the car for a few months and never took notice of the gauge until today when I noticed the reading seemed lower, for reference here is what my cluster looks like, specifically the tachometer http://s153.photobucket.com/user/demandchainguy/media/cluster1.png.html .So I was just seeing whether anyone else would know seeing as google isn't very helpful for this kind of problem.

That link doesn't work.

I don't think it's a fuel pressure gauge. I can't think of a are that has a fuel pressure gauge stock.

@Ben C34, heres a link off an ebay listing for a spare cluster http://i.ebayimg.com/00/s/MTE5NVgxNjAw/z/KNAAAOSwstxVfVkh/$_75.JPG,its hard to see but at the bottom of the tach is a smaller gauge, that is from what I can make of it seeing as it reads kg/cm squared, is fuel pressure.

As above, it's oil pressure.

All good.

Ohhh, with that, I found another thread that had this same problem. I feel like a fool slightly for that, but again appreciate the help @Ben C34 and @Stagea97. Should be an easy fix now, again cheers for helping out!

@Hadouken , Never had a car with an oil gauge, and with only a vague symbol to go by and panicking my car was about to go caput, I thought it was for fuel, now after being told its actually a oil pressure gauge, and the other thread mentioning that 2kg per cm^2 sounds about normal. I'll have to check it out myself in detail tomorrow.

That's 28psi at idle. All good.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
