If you’re running an aftermarket positive displacement lift pump like our PowerFlo on your Duramax our fuel primer bulb sealing kit will allow you to eliminate the leak prone primer bulb from your fuel system. The sealing cap includes a 1/8” NPT port to feed a low pressure fuel gauge or cap it off with the included NPT plug.
Kit Includes:
- Fuel primer cap
- 1/8”NPT O-ring plug
- Fasteners (includes 8-32 and M4 screws)
APPLICATION NOTES
The kit includes two screw options (standard and metric) - thread in by hand each screw type and use the thread pitch with the best fitment. There is variation amongst the model years, so always test first by hand to verify the thread pitch on your vehicle.
