Fuel Pressure Guage - HELP!

Does anyone in the lower mainland area know where I can get me a fuel pressure guage? Candian tire no longer stocks them. Nor does lordco. Lordco can order one in, but those are pro-series kits which are like 600$+

I just want a rougly 100$ or less fuel pressure guage but cant seem to find any places which sell them. Anyone able to help me out finding a place?

mopac has fuel pressure gauges at decent prices. I have a used electric fuel pressure gauge (2 5/8", autometer) for sale if you want it.

THe problem with the cheaper gauges is that they are mechanical. Since you cant run a fuel line into the cabin to the gauge for safety reasons, you need to have a fluid filled line which is pressurized at the fuel line by a diaphragm. These diaphragms have been known to fail from time to time with bad results.

be sure to check out best buy as well as ebay. but yeah you get what you pay for and the electric ones are the best. but not 600 best, im sure you can get one for under 300 with the sending unit if you shop around.

Great info guys, I'll check out mopac for the electrical units, i definatly want something that will last. I guess i might as well get a pod for inside right?

Any recommendations on what would fit a 95Z really well(Dark grey interior)? Don't want some weird funky pod looking out of place inside my car :)

a pillar pods, there like 30 bucks. maybe you can buy one off of bunker hes got like four hanging around his house. i think i got like three too. 20 bucks and its yours, its a dual gauge pod though.

and best buy should be bale to beat blowpacs prices.

get best buys...and go for auto meter colbalt...expensive but pimp:bow:

what style is yours craig? is it full sweep to 100 psi? and how much u want for it? :)

I'm lookin for a white faced one, I think its ultra lite?

The only way to get accurate fuel pressure is with electric sender or a mechanical gauge mounted on the hood. The problem with the ones that use a fuel isolator is that the liquid on the gauge side of the diaphagm heats up with underhood temps and raises the indicated pressure. If you do get one of those, mount it in the coolest spot you can find underhood. Otherwise it will read way off. You are better to spend a little extra $$$ on a electric sender that threads onto your test port. I know Snap-on makes them for the Vantage so you can see fuel pressure/spikes (I have one at work), but they are stupid expensive.

mine is an ultra-lite white faced.... full sweep to 100 PSI. it is the larger style, 2 5/8".

let me think on a price I will post tomorow.

I have a single 2 5/8" a pillar pod ... if anyone buys craigs gauge .. i'll throw in the pod for free ..

Cory, so its only the mech. ones that may give problems?

the electric ones are completely accurate?

thx!

correct - the electric gauges are accurate and safer (no risk of diaphragm rupture).

for mine, I'd like 125 USD or 175 CAD.

Hey Draco, will these fit the pillar nicely in our cars? Can you get differnt pods? (arre the pods a standard size?) never really gotten any guages added other than what came with my car :)

The pillars look just fine from what I've seen. Most folks run 2 1/16" gauges in their pillars, not the larger gauge that I have - however there are pods that fit these larger gauges just fine (I believe Payam ran a dual 2 5/8" pod).

On my old firebird, I put the gauge in one of the A/C vents since it was a perfect fit. You obviously cant do this on a Z since the vents are not round.

Yea, but at least we can fit the Scanmasters :D

The electric senders are definatly safer and more accurate. They do not require any hoses or rubber diaphragm that can fail. They use a metal diaphragm (the end of the sensor) that either threads onto your test port, or you may need a brass/aluminum adapter fitting. With mechanical gauges you can get false readings over 5psi from the heat. When I buy electric senders (and I need them to be accurate) I will test them. Hook them up, and also have a GOOD mechanical gauge hooked up. They should read the same. If not you either buy another sender or add/remove a resistor. Most pressure senders will be very accurate but sometimes you have to compensate for the resistance of the wiring etc. If you have 100ft or wire the gauge will read different than 4ft of wire. Anyhow, for most applications thats going overboard. Buy sender, thread it on, wire to the gauge :D .

incorrect. AFAIK, autometer never made a dual 2 5/8" pod .. i ran 2 single 2 5/8" pods

Craig, i'm assuming everything comes with this guage in order to hook it up?

All wiring/sender/etc...

?

yes, I will also throw in the swivel fitting to connect the sender's stainless steel line to the fuel rail schraeder valve if I can find it. You can borrow my valve core removal tool also. Everything is over at my parent's house so I need to go dig it all out hehe.

Removal tool? I'm confused :)
I thought you just attach the sensor part to the schrader valve and the rest is wires?

nope, you need to remove the valve core from the valve in order for the fuel to enter the line which goes to the sender unit.
