Well, I got done with it today. It was a piece of cake. The only thing I didn't like was waiting for the pressure to bleed off when unscrewing the schrader valve. It's all good though, I had a rag underneath the fuel rail right under the valve and a rag on top of it. I didn't get any fuel on my engine.

My pressure readings on the gauge are as follows:

Idle: 32-33 PSI
Cruising at 60 MPH: 34-35 PSI
Moderate Acceleration: 35-36 PSI
Hard Acceleration: About 40 PSI
WOT: 52-54 PSI

Sounds about average right?

I need to mention that I have Walbro twin 255lph fuel pumps and stock 42# injectors right now. Should I see a change in pressure once the 60# injectors are installed?

I also took some pics for you guys. Here you go...

 

Did you hook that up directly to your schrader valve with braided fuel line to your guage?

From your picture it sure looks that way. If so keep a gun in your truck so if it leaks in the truck and catches a fire a bullet to the brain is much better than burning to death.

 

Ity's braided fule line to the sender. No fuel in teh cab, and no weight on the rail to crack it, which I have persoanlly experienced and it's NOT fun

Looks like my setup.



Great job SW!!! And your FP looks spot on with mine as well.

 

It's an electric fuel pressure gauge.

 

Thank you I feel much better

 

You should not see a change with the 60# injectors. The numbers you are seeing are fine if you are making 13-15 lbs of boost. Basically, your static pressure is 39psi, so you should see that when you have 0in. of vaccuum. For every 2in. of vaccuum, your fuel pressure should drop below the static pressure by 1psi. For every lb. of boost you see, the fuel pressure should increase over the static pressure by 1psi. Sit in your truck and watch how your boost/vac and fuel pressure gauges work together and the above should make sense.

how come ya didn't just screw the sender into the shrader valve?? that's what I did, much less to hook up than having a braided line

 

The vibration of the engine and bumps over time "could" lead to it cracking and spraying fuel all over your hot engine. I have personally pulled this feat of ingenuity off in my Typhoon and it scared the living **** out of me. Remote sender location for the win..

 

I thought it would be a lot of work to hook up fuel pressure gauge although electric gauge is probley the way to go.

 

That ^^ and a lot of people have had the sender prematurely fail on them from mounting it directly to the rail. Engine vibration over time can cause the sender to fail. By mounting it remotely you eliminate the engine vibration on the sender.
