22. Fuel Pressure Sensor Installation
Use the J5 connector harness 790719-X labeled FUELP.
Mount the pressure sensor to the pressure line using a flexible hose and fittings (not supplied) as depicted in the
drawing below. Use Aluminum Clamps MS21919WDG25, or WDG14 to mount the pressure sensor to engine
mount structure or firewall. Do not mount the sensor’s directly to the engine. Connect the other end of the hose to
the existing pressure line. Later, you will connect the pressure sensor to the four pressure sensor wires through the
supplied 4-pin connector. Part No. 790775() required for Carburetor engines OR Transducer PN 3060-17 for
injected engines. PN 3060-17 is a resistive and requires two wires with no polarity.
For Sensym sensor (shown below), crimp the four pins of the female Molex connector to the harness,
matching the wire colors. Secure to firewall with Aluminum Clamp MS21919 WDG14. For injected
engines use clamp MS21919WDG 25.
23. Adding a non-primary gauge to the system
Requirements: new generation EDM-930 with software from June 2010 or later
Steps:
Download EDM Config from JPITech.com (On Software Downloads page)
After “installing” EDMConfig on USB stick, insert into EDM-930 and hold STEP/LF during power up
Step through EDMConfig messages to “EDIT GAUGES” message
o STEP through gauge position to select the EDM-930 gauge to be replaced with FP
o Select “MODIFY” function
On gauge edit screen STEP until the gauge name is selected, then tap MODIFY
§ Tap YES to confirm change of channel
§ Tap NEXT until FUEL-PSI is displayed, tap SAVE
§ Tap YES to confirm change, tap NEXT
o Use NEXT and PLUS/MINUS keys to adjust color bands and limits for FUEL-PSI gauge
o Tap SAVE to save changes to the gauge, YES to confirm
o Tap DONE to exit gauge editing mode.
Tap NEXT repeatedly until EDIT CHANNELS is displayed
Tap yes to edit channels
o Tap STEP several times to select FUEL PRES input channel
o Tap ENABLE key to enable the input
o Tap SAVE, then YES to save change to channels
Tap STEP key repeatedly until prompted to exit configuration, EDM will restart with FP enabled
24. Fuel Pressure Sensor Installation
Use the J5 connector harness 790723.
Mount the pressure sensor to the pressure line using a flexible hose and fittings (not supplied) as depicted in the
drawing below. Use Aluminum Clamps MS21919WDG25, or WDG14 to mount the pressure sensor to engine
mount structure or firewall. Do not mount the sensor’s directly to the engine. Connect the other end of the hose to
the existing pressure line. Later, you will connect the pressure sensor to the three pressure sensor wires through
the supplied 3-pin connector. Part No. 159935A is for non-turbo engines and PN 159938 had a second port used
to measure the upper deck pressure on turbo charged engines.
