If you are installing this into a diesel vehicle, the fuel pressure sending unit can be installed to your lift pump, injection pump, or the fuel filter housing.
If you are installing this into a regular gas vehicle, the fuel pressure sender can be installed on your fuel rail.
If you are installing this into a Dodge Diesel Truck, the fuel pressure sender can be installed directly into the fuel filter housing using GlowShift's Banjo Bolt. GlowShift's Snubber Valve would also need to be installed to the fuel pressure sending unit.
