I have an electric fue pressure gauge, where can i get a ntp fitting so i can hook it to my schrader valve?

 

It isn't an NPT threaded fitting, it's a -4AN female fitting...

 

Summit has them or any speed shop. I have a T coming off the schrader now one side goes to the guage and the other to my fuel solenoid for N20. However, before I added the N20 I just ran the steel braided hose straight to the schrader only fitting needed is the one on the end of the hose. Autometer makes a kit that comes with 3 feet of steel braided hose and the fittings already in place, that works awesome, it what I run now. Cost about 30 bucks but was well worth it since I didn't have to try and put a fitting on the end of the braided line which is a nightmare.

 

is your gauge mechanical? mine is electrical and i dont think i need hose just the fitting

 

Suggestion.... you don't want the weight of the electrical pressure sensor hanging off the Schrader valve. That fitting is only swedged on the fuel pipe, and will break off very easilly. You also have to be concerned about clearance between the pressure sensor and the cowl, remembering that the engine moves under high torque loads.

My solution was to get an NOS PN-17535 -4AN 90-degree swivel fitting. That gets the connection pointed away from the cowl, and the "swivel" feature allows you to properly align the fitting in the direction you want, without over-tightening it, and damaging the fuel line.

From the -4AN fitting, get an NOS 24" hose, with a -4AN on one end, and a 1/8" NPT on the other. Use a common 1/8" NPT brass coupling to connect the sensor to the hose. This allows you to get the sensor away from the heat and vibration of the engine, maybe tucked behind the PCM where it is safe. If you need more than one fuel connection off the Schrader, use a "tee" in place of the "coupling" and you can add a fuel supply for a wet nitrous system, a fuel pressure safety switch, or a small underhood fuel pressure gauge.

Or... try mounting the sensor this way.

 

thanks for the advice but my piece of sh**dell laptop messes up each time i try and click on a link, it goes to a blue page and wont load. ok where do i get this common npt brass coupler to connect the sensor to the hose?so doing it this way is best even though i have an electrical gauge

 

Any decent hardware store will carry a 1/8" NPT brass coupling. Probably less than $1.

I think keeping the electric sensor off the Schrader is a good idea. Keeping it away from heat and vibration is a good idea. I ran my AutoMeter electric fuel pressure gauge that way for about 3 years, until I did the work on the fuel rails, and had an aluminum 1/8" NPT bung welded to the passenger side rail.

 

is the brass coupling 1/8 on each end?

 

wil this hose work?

It should, providing your gage sending unit is 1/8" NPT..

 

im pretty sure its 1/8 its an autometer electric pressure gauge
