Fuel Pressure Gauge with nipple connections for easy, quick installation, use with any fuel injection hose type.
0-100psi, assmbled and sealed, ready to install.
Please note, this should be installed in the fuel feed line, between the fuel pump and FPR.
IN OTHER WORDS, NOTAFTER THE FUEL PRESSURE REGULATOR WHERE THERE IS ZERO PRESSURE, BUT IN FRONT OF IT, BETWEEN THE REGULATOR AND THE FUEL PUMP, WHERE THE INJECTORS FEED FROM, WHERE THERE IS PRESSURE, SO YOU CAN MEASURE THE PRESSURE WITH THIS GAUGE - MAKE SENSE??!
