Fuel Pressure Gauges
Hey guys I am planning on buying a fuel pressure gauge to mount under the hood in the engine bay for easy future troubleshooting.
Can I just buy one of these, remove the shrader valve on the rail and install it and leave it be? How much fuel drips out from the rail when the valve is removed?
Lastly what's the difference between gauges with water and without like these (is one preferred over the other?):

Thanks!

The diff. between gauges is the liquid filled (oil) remains somewhat steady when using whereas the non-liquid filled gauge tends to fludder.

The liquid helps to dampen the vibration under the hood of the engine rocking around.
I picked mine up from Exotic Muscle fittings and all.
You shouldn't get much fuel out of the rail if it's been sitting, if you were just running an dthere's pressur ebuilt up, that's a different story.
Use a rag and a screwdriver and press the shrader valve to release any pressure before you take the valve out, then install. You should not get any leaking under hood if you install properly.

You can also use a mechanical gauge inside car but require a isolator to keep the fuel in engine bay.
