Fuel pressure gauge rail mount install pics

[98cobradan]

does the gauge just screw right onto the rail, where the fitting is or do i need an adapter to make it fit. DO i have to relieve the fuel system first?? DO i need a 90 degree elbow fitting so that i can see it, instead of screwing it staright on? anyone have a pic of how it looks

lookin at gettin this one the 100PSI

I always thought you screwed it into an adjustable fuel pressure regulator.

they can if u buy one with that guage mount on the regulator.

I havent done one yet on my 97, but n the Foxes I have owned, I purchased a 'T' fitting, screwed the pressure gauge into it so it was 'face out' , screwed the 'T' into the fuel rail, and then reinstalled the schraeder valve.

TO relieve the fuel pressure, I'd unplug the fuel pump inertia switch in the trunk, and then run the engine until it stalls. This is the procedure that my Chiltons recommends.

*BUY A CHILTONS/HAYNES MANUAL*. I've taken to leaving mine beside my computer these days to answer questions for those of you that choose not to read/cant read. 60-70% of the questions I see asked in here are answered in these manuals and take *seconds* to look up. The manuals also detail safety warnings and instructions I often dont include for brevity, but said warnings and instructions need to be followed nonetheless. You've been warned.

the gauge is 1/8 npt and the fitting in the rail is 1/16 npt

this one doenst go into the shraeder valve. i saw a pic yesterday on here of one but cant find it where i went. there is a pressure valve on the passenger side rail, right up front, looks like a tire valve stem.

 

[98cobradan]

the gauge is 1/8 npt and the fitting in the rail is 1/16 npt

cant be a 1/16. that means the fitting is like 2mm big lol. i just measured its a 1/8 fitting on the rail

 

[98cobradan]

right here guys, looks like a tire valve stem, i was told the gauge mounts up right there

Tire valve stem == schreader valve, no?

Bleed your fuel pressure, unscrew the valve, rig up a "T" fitting so you can remount your pressure gauge and the valve at the point shown in the above pic.

yup, thats pretty much it...

and i wouldnt let the car run to releive pressure. just let it sit over night, take that cap off, get a small screw driver and a few rags, push the schrader valve in and let it leak down.

that is the pitch of the threads so yes it can be 1/16

 

[98cobradan]

ah thought u meant the diameter of the rail fitting. are u sure its that then cuz i just ordered a 1/8 male femal adapter for it, instead of a 1/8, 1/16 adapter

this is what i ordered along with the aeromotive FPR gauge

dohhh thought the shreader valve was located somewhere else

yep the car will be sitting over night, i will however hit the enertia switch then run the car till it dies, then let it sit over night. im also installing a Aeromotive FPR, any tips for that?? seems straight forward, two bolts and a vacuum hose. im following these instructions from aeromotive

if you are installing the AFPR as well, just mount the gauge to the regulator body. Thats what i did on my 5.0. I haven't done it to the cobra yet. Get the aeromotive gauge and it screws right in...

as for relieving fuel pressure...2 ways.... either press the inertia switch and run the car til it dies, then crank a few extra times... or let it sit, and pull the valve core out and get some rags...

 

[fourvalvegt]

im pretty sure your going to need a 1/16th male to 1/8th male adapter for that. most ports for fuel pressure gauges on aftermarket regulators are 1/8th to begin with and thats why they are 1/8th gauges

i just ordered the aeromotive gauge to go along with the aeromotive FPR. know does this port on the back is where the gauge screws in?? cuz the guy i got the FPR from said it doesnt go in the regulator itself, but on the fuel rail

Now do i leave the shreader valve open then screw the gauge and adapter on?? otherwise there will be no pressure correct?? Does it stay pushed down or pulled opened?

well ill find out 2mora when they get here. i wish someone that has a gauge on the fuel rail would chime in that knows "exactly". not sayin u dont.
