Who Uses A Fuel Pressure Gauge?

[N1GTR]

Hey all,

Who's using a fuel pressure gauge on their car?

Im getting concerned about fuel pressure, so whats good, whats bad, where to buy etc

All info is appreciated

You want an inside one or an engine bay one? I'm going to take a guess that you want an interior one, in which case my comments are going to be pointless

I'm using a Turbosmart under bonnet one which is liquid filled. Is a very good price, easily readable and the liquid filling stops the needle from vibrating around giving bad readings. Very happy with it.

Reason I have mine is to check the max fuel pressure for choosing nitrous jetting.

yep, I use a Defi BF fuel pressure gauge. very good. easy to install, easy to use, easy to read and has one awesome feature I've not seen on any other brand. if you also have the boost pressure gauge (and who hasn't) it can display what they call 'differential pressure' so what it does is remove vacuum or boost from fuel pressure so you can see the actual pressure. this makes it very easy to spot if something's going wrong. see you have the regs base pressure (approx 3 bar in a skyline standard) and then vacuum reduces it, and boost increases it. so when driving it will be fluctuating all over the place. switch the gauge on to diff mode and it should just sit on 3 bar moving only slightly. because it's showing you the difference between total fuel pressure and boost pressure. very handy. and makes it very easy to diagnose any fuel supply problems etc.

I am using one like PM-R33 as i had the same concern as you N1GTR about one of my two bosch 044s failing.

I got mine for about $35 from hi-octane and its bolted on to my SARD fuel pressure regulator.

Though i feel i need one in cabin like Baron as it does sound a lot safer as you'll be able to see it whilst driving. Though it depends if you are willing to spend $300 or so on the defi gauge + another $150 or so on the control unit

I guess you can afford to spend $450 or so after spending that much money and time on your 30/26 right?

Thanks guys!

Yes I'm after an inside one, the ones in the engine bay are nice but they're useless when the car is moving. The major concern I've got is that I go for a drive and one fuel pump dies, then stand on the loud pedal and you can all guess the rest

Baron I've got the defi triple cluster that replaces the stock dials in the centre, I don't have a seperate boost gauge cause the ebc does that and it's not something I'd look at anyway (there's enough to worry about when you're up it). Does the gauge you've got have a warning or memory recall for a minimum value? The defi gauge in my supra is a bf boost gauge and it has peak recall etc of course with the control box2, but peak isn't a value I want for fuel pressure, if it has a warn at a user defined preset minimum level that would be perfect!

Destrukshn do you have a pic of your one please? I know what you mean, the spending never ends!

[PM-R33]

Yeah fair enough.

Like I said, mine was only for doing the nitrous jetting on the dyno and for $40 odd dollars I figured why not.

[destrukshn]

N1GTR, here you go

I am pretty worried about one pump dying too

Will have to search deep within my pockets to see i can afford defi's

[XRATED]

Greddy gauges..... US ebay.... cheeeeep!

Will be installing a mechanical gauge straight onto the reg as well.... easier for set up on the dyno/nitrous tuning etc.

yeah just like the fuel pressure gauge the defi fuel pressure gauge has a min warning, and also peak hold and of course record functionality. I would seriously chuck the current boost gauge and controller from the supra into the GTR and add the fuel press gauge to go with it. being able to have it display the differential pressure is a massive advantage over other gauges and really useful. makes it so easy to diagnose reg problems, pump problems etc. and of course you don't have to watch it all the time. can just do a quick run on record then play it back later, or just watch it a bit, set the warning level and then leave it alone.

guise, if you want an in cabbin one what other parts do you need? as above im stressed that my fuel pump is going to die, how do i go about setting up one for the interior? and also some rough prices to on something cheap?
