3. FUEL FILTER & FPR SETUP
1. Remove the OEM fuel line from the chassis mounted fuel filter. Retain the OEM
banjo bolt but discard the used crush washers. Install the provided banjo fitting
with new crush washers mounted below and atop the fitting.
2. If desiring to mount a fuel pressure regulator gauge onto the AEM 25-302 Fuel
Pressure Regulator, now is the time to install. The gauge requires a good
amount of effort to install onto the FPR, so if you try to install when the FPR is
already mounted onto the fuel rail, there is a great risk of damaging fuel line
fittings and causing a leak. Karcepts, Inc. will not be held responsible for any
broken fuel fittings or fuel leaks caused by improper installation. To begin FPR
gauge installation, wrap the end of the male 1/8” NPT thread with Teflon tape.
