Do I need a Fuel Pressure Adapter for my Chevy/GM Duramax 6.6L?Updated 3 hours ago
To obtain a fuel pressure reading on a 6.6L Duramax, an aftermarket lift pump is required. Some aftermarket lift pumps have built-in ports that allow you to install a fuel pressure sensor directly into the pump.
If your lift pump does not have a dedicated sensor port, the GM Duramax 6.6L Fuel Pressure Adapter provides an alternative installation point by allowing you to install the sensor directly into the factory fuel filter housing for an accurate fuel pressure reading.
