GlowShifts Fuel Rail Thread Adapter for Ford cars and trucks makes it easy to install aftermarket fuel pressure sensors. If your Ford has a multiport fuel injected engine with a Schrader valve on the fuel rail, this adapter installs directly to the fuel pressure test port. Machined from aluminum, the Ford fuel rail pressure adapter also has a 1/8-27 NPT fitting for a direct-mount fuel gauge or gauge sending unit.
