As the truck accumulates age and mileage, the O-rings and fuel system seals in the factory filter head can deteriorate, allowing air to enter the system and causing the fuel system to lose prime, resulting in hard starting or difficult cold starts. This budget-friendly rebuild kit offers an easy way to refresh the seals without replacing the entire filter head, making it an ideal choice for servicing an aging or troublesome fuel system.\u003c\/p\u003e\n\u003cp\u003eThe kit includes four specialty Viton O-rings and two plunger seals, providing the key sealing components for rebuilding the filter head. The high-quality Viton construction is designed for durability in a diesel fuel system, while the straightforward installation makes this a cost-effective repair for trucks experiencing fuel system priming issues. In 2011 and newer-style filter heads, one of the small O-rings is used for the bleeder screw, and the other can be disregarded. DmaxStore also recommends replacing the fuel filter while rebuilding the filter head to ensure the entire service is completed with fresh components.\u003c\/p\u003e","brand":"DMAXStore","offers":[{"title":"Default Title","offer_id":67625991635309,"sku":"DMAX-DMAXORING","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/1e2ff3e3-bd56-442d-9263-2a23f1161f15.jpg?v=1791321511","url":"https:\/\/dieselpowerproducts.com\/products\/basic-filter-head-o-ring-rebuild-kit-01-16-gm-6-6l-duramax-lb7-lly-lbz-lmm-lml","provider":"Diesel Power Products","version":"1.0","type":"link"}
