Fuel Pressure Gauge Install

[donut_kng]

Just wondering if anyone has ever installed an electronic fuel pressure gauge in ther R33?

As I am trying to work out whats the best way/place of instlling the sender, im wure it isnt that hard by I have neevr done a Fuel pressure gauge before..

Any help appreciated.

Hi m8

Free bump,

I have just started looking at this myself as I am paranoid about fuel pressure dropping and blowing my engine.

Have you got an electronic gauge yet? if so what have you gone for?

I am also trying to egt some answers on the forum in the U.K so if I find anything out will let you know.

I've put one of these in a 32gtr, just put the sender into the fuel line where it heads into the fuel rail, run the wiring to the cabin, source ignition, headlights and earth...done!

I had trouble with interfearance from the other gauges that I ran ina little loom (5 other gauges) so run the wires on their own

Ive got an autometer electronic one, rocket part number AU3363.

Cool thanks for that mate. Just to clarify, you put the sender in with a T-piece obviously before the rail, but where abouts exactly?

Is there any real risk regarding loss in pressure as said?

[Duncan]

put the sender in anywhere between the fuel filter and the rail. I used a T-piece - double ended barbed fitting which had a thread for the sender (can't remeber what thread it is).

The interference was from the other wires that I ran with the fuel sender wire, the fuel flow itself was fine

[donut_kng]

Do you still get an accurate reading even though its before the fuel reg ?

I was thinking of doing it on the return line.

[heller44]

The return line is low pressure, just dumps back into the tank.

The fuel reg is at the end of your rail, not the start of the rail, think of it as holding the pressure up in the line before it. Like holding your finger over the end of a garden hose to hold the pressure at a set level in the hose..

Duncan, what problems were you getting from the interference? I've just wired in some autogauge gauges and the fuel pressure one is playing up, reading too low and dropping when the headlights come on.

[donut_kng]

sounds like you may have a shitty earth/ground - do it straight to the body bare metal

[Craved]

last time i priced these things they were $800ish each

anyone got a more recent price on the elect fuel presure guage?

[_Scotty_]

The one I'm using only cost about $80. I'm hoping it is just the ground, but the other gauges are using the same point and seem to be working fine. I'll have to get the multimeter out and muck around with it later.

[donut_kng]

the autometer Im useing was about 400 bucks and its electronic.

autogauge are the ebay ones aye?

[_Scotty_]

Yeah you can get them on Ebay, although I got mine from Just Jap. They're pretty cheap but I've used them in the past with no problems. This one is giving me the shits though, the low pressure warning keeps sounding as I drive. Time to check the wiring...

[_Scotty_]

Got it sorted, the point where I grounded the senders wasn't good enough. They're now wired to the chassis and are working correctly. Cheers for the help.

Anyone found a decent gauge to put directly onto the rail? I'm not really interested on monitoring the pressure whilst driving, more so whilst on the dyno and idle.

[donut_kng]

autometer does like a 1 3/4 inch one for memory, all the big 8's have them.

I said decent. I won't touch Autometer!

[donut_kng]

well what brand did you have in mind.

autometer is good shit

[PSI Parts]

Something with proven accuracy not just pretty looks. You might want to investigate your claims that autometer is "good shit" just because a company is big doesn't make it good. Although I don't want to turn this into a debate about gauge brands.

I was thinking something like Earls, however most brands only have a 15 or 30psi gauge designed for carby setups.

[Craved]

yet to find any guage that is tested for accuracy

just checked autometer website adn Defi - no listing of the range of accuracy available.
