Where is the Schrader valve on the 1988 2.3 liter Ranger 4 cylinder engine? I think it should be on the fuel rail but I can't locate it. Shouldn't this year have one in order to test the fuel pressure?

My truck wouldn't start but would run briefly on starter fluid. Found a kinked fuel line and the frame fuel pump was not working. Replaced both. Truck still won't start so I need to check for fuel pressure at the rail. But I need to find the Schrader valve to do that. Please clue me in if you know.

Thanks!

My 95 is under the upper intake manifold on fuel rail.
