Software updates: Attribute programmer R82003 may be used to activate and set the integral
warning light, adjust the backlighting, and filter out pulsations in the measured pressure. For
optimum filtering of pulsations set Sensor Scan Rate to 100 and Weight to 0.1.
12 Engine specific information: Cummins 1989-1998 and Powerstroke 1994.5-1997 – if using
mechanical lift pump, add a needle valve (R7742), followed by 24” minimum of compatible hose
such as grease gun hose (may require female-female coupler), then the sensor. Tighten the needle
valve fully then open it ~1/8-turn. If gauge oscillation is still evident, add either a 2 nd needle valve
(R7742) or a snubber (R7800) between the hose and the sensor. Powerstroke 1999-2003 –
installation on fuel bowl port requires a 7/16-20 SAE O-ring to 1/8” NPT adapter (available from
hydraulic supply store or many diesel performance dealers). . Powerstroke 2003.5-2007 –
installation on fuel bowl port requires an M12x1.5 to 1/8” NPT adapter (R7962). Cummins
1998.5-2002 – Injection pump oscillations may require the addition of a needle valve (R7742)
between the fuel system and the sensor, start with it adjusted at 1/8-turn open. If using a stock fuel
filter canister, install the sensor &/or needle valve with a tapped banjo bolt (R7743) at the filter end
of the main supply line from the filter to the VP44 injection pump. Cummins 1989-present – If
using stock fuel supply lines with a banjo bolt, a tapped banjo bolt (R7743) is available for installing
the sensor. Duramax 2001-present – a fuel pressure gauge is only used with an aftermarket lift
pump; install the pressure sensor in the test port of the lift pump.
