Fuel Check with fuel injection.

Robert Swartz · 07-09-2012, 10:23 PM

Now if I decide to upgrade my car to true stocker status at a later date. I will have to do this. It's easy to set up a check valve with a carb equipped stocker. How do you do it with a fuel injected car.

This engine has a fuel regulator mounted onto the end of the fuel rail. Can you tap into that and put a check valve in before the regulator?

Here's a picture of the engine. Open to ideas and suggestions.

Just undo a line from the fuel rail and put on one of these. Be sure an hold the cup tight.

My cheap-azzed way was to plumb in a lawn mower fuel tank valve from NAPA and a weather proof starter button that grounds the fuel pump relay when pressed. Both front/left side under the hood. Open the valve, press the button & fuel flows. You can spend more on nice valves. I rigged my deal up before I saw the fancy stuff. Mine works just as well. I don't have a show car anyway.

i hooked mine up to the schrader valve where you hook up the pressure gauge. jegs has a nice adaptor. it comes with their fuel pressure gauge for a 5.0 mustang.

Most of the Quads didn't have a pressure tap. If it does then get the adapter. If not I've drilled and tapped the fuel rail for 1/8 NPT then install any type valve. I'd like to give a big old thank you to GM for not providing a fuel pressure tap on alot of their engines since that's the first thing I check on a driveability issue. Joe

I have the press and pull fitting on my fuel rail. I just take the line off and I have a remote start panel in the engine compartment.
It's worked for 6 years so far.
