Fuel Pressure Problems

[seanski96]

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.

You sure that's the right pressure reading?

Why do you even have a fuel pressure gauge on it?

[seanski96]

@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.

It's a n/a. Remove gauge. Save weight? More hp!

[seanski96]

Its part of the gauge cluster, edited the original post with the reference link, it's not an aftermarket gauge anyway.

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!

[Ben C34]

No worries man. At least you figured some stuff out!

And thank you @seanski96 I had no idea we could tag people.

[Hadouken]

lol

lol

It actually works. I got a notification telling me he mentioned me in a comment.

[Hadouken]

I lol about oil pressure gauge. Not tag. Tag cool

Also mate, do you think that 2kg per cm^2 sounds normal or could it be my sender unit being buggered?

[seanski96]

@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.

Cheers man, this and a separate thread mentioned that its fine since the oil becomes thinner at regular temperatures
