I don't see the same picture as the one you attached, not sure what am looking at is it by end of the valve cover close to the engine oil fill cap or under the intake?

This should help. Let me know if you still can't find and I will see what else I can get.

Looks like this is the fuel supply line so this sensor in the fuel line should be it. Easiest way is to unplug it and then check codes with the key on. You should have an active code for the sensor.

Hi again. Hay, I attached a picture of the T for testing pressure when they don't have a schrader valve. You should be able to get one anywhere.

Take care.

If you have that then you will need still need to find two fittings to make it work. One that goes into the actual fuel supply line and then just connect it to the one side of the T fitting. Then the other side that goes from the T fitting back to the rail where you will need the other fitting to go on the rail. The the gauge just threads onto the threaded part of the T fitting.

I sketched this out on Joe's picture.

So pretty much adding a sensor within the line itself, the sensor being the gauge, instead if relying in the fuel pressure sensor.

Exactly. You are simply verifying the sensor is telling you the correct pressure by using a "known good sensor" which is the gauge. This way you know if you have a pressure issue or a sensor issue.

But the line is going to bring in a lot of fuel once I disconnect it, not like a valve.

You mean when you unhook the line to put the gauge in line? Yeah, you will need a towel or rags. Once the existing pressure bleeds off it will stop. Clearly get everything hooked up with the key off so you don't have the pump creating pressure while you are trying to get it hooked up. You will not get much fuel out of the line but there will be some when you unhook it.

Then once everything is hooked up, cycle the key a few times to get the pump to build the pressure and prime the line and check for leaks. If there are no leaks, go ahead and start you pressure checking.

Thanks. So the line that already has the fuel sensor within it is the one to unhook. And so one side of the fitting will be metal while the other rubber, since we are keeping this T in the line.

Yes. That is the line that you need to measure the pressure on. Correct.

Changed the sensor on too in the rubber line, can you see any difference here?

Is there an option for "current fuel pressure"? I don't see it there. Thanks
