If you're working on the fuel system of your 2001-2016 GM Duramax truck, like a Silverado or Sierra 2500 HD or 3500, and need to address a leaky primer bulb seal, this kit from Fleece Performance is what you'll want. A worn-out seal on the fuel primer bulb can lead to air getting into your fuel lines, which can cause hard starting, rough idling, and even stalling. This kit is designed to replace those failing seals and get your fuel system back to sealing properly.

Fleece Performance is known for making well-built parts for diesel trucks, and this sealing kit is no different.
