Chevy & GM Duramax 6.6L Fuel Pressure Sensor Adapter
NOTE: An aftermarket lift pump must be installed to complete this fuel pressure sensor installation.
1. Remove the bleeder screw from the fuel filter housing
that is located next to the hand pump.
2. Thread the fuel pressure adapter into the fuel filter
housing’s pressure port.

Note: Be sure to tighten the fuel pressure adapter
so that the supplied o-ring seals the pressure port
on the fuel filter housing.
3. Once your fuel pressure adapter, sensor and gauge are
installed you will need to bleed out any air that is left in
your system. Follow the steps below to properly bleed
the system.

Loosen the fuel pressure sensor adapter so the O-
ring is not sealed.

Press down on the hand pump until fuel comes
out of the pressure port.

Once the line is bled, re-tighten the fuel pressure
adapter so the O-ring seals properly.
4. Install your fuel pressure sensor directly into the female
end of the fuel pressure adapter.

Note: Be sure to use a fuel rated sealant on the
sensor threads to ensure a tight seal.

Note: It may be necessary to install the fuel
pressure sensor remotely; this depends on the size
of the sensor you are installing. Use a fuel rated
line to remotely install the sensor away from the
fuel filter housing, the firewall is the best location to remotely mount your sensor. A fuel
pressure sensor relocation kit is available on www.GlowShift.com.
5. Finish installing your fuel pressure gauge by following the instructions that are included with it.
