Installing / Replacing the optional Fuel Pressure Sensor
An optional fuel pressure sensor may be used with your system to provide additional
information to the ECU and for readout on digital smart gauges and displays over the
CAN network. It is also used by the system for automatic fuel pressure compensation if
the sensor is in the system. The pressure sensor should be mounted in the fuel rail or
crossover line prior to the fuel regulator. In all cases, but especially if the rail is drilled
and tapped for the 1/8” NPT thread: cleanliness is a must to avoid contamination of the
fuel system and potential engine or injector damage. After machining and during
assembly/disassembly – clean the rail assembly and associated lines thoroughly. Make
sure there are no chips, particles, or overhanging burrs that could break loose.
A typical sensor installation is shown in figure 16.
