Underhood Fuel Rail Gauge Kit For The Porsche® 928
Application - all 1985-1995 Porsche® 928 with screw fitting at the front of the fuel rail.
Background: On most 32v Porsche® 928's, there is a screw fitting on the
front of the right-side fuel rail that is currently capped off. This
fitting is used by Porsche® mechanics to attach a fuel system gauge to
perform air/fuel ratio testing and tuning.
The Kit: We provide you with a high-quality glycerine-filled fuel gauge
that you can permanently attach to the fuel rail with the fitting supplied.
This special fitting has the correct metric threading on one side, and
the correct gauge threading on the other. An O-ring is provided for
a positive. Gauge does not require any wiring, and is HD industrial
grade, durable and designed for years of use.
Uses: This is the best way to tune your 928, adjust FMU or EMI/EMU systems, and confirm your fuel pump is producing the right pressures in real-time at all engine speeds.
