Find the Fuel Tank Sumps & Suction Tubes you need when installing an aftermarket lift pump in your 2004.5-2005 Chevy/GMC 6.6L LLY Duramax. Most fuel tank sumps are designed with an o-ring gasket for a leak-free seal and feature a no-tank drop installation. The suction tubes offered use a larger diameter fuel pickup and in some cases can work with the stock fuel sending unit. Both the suction tube kits and fuel tank sumps are manufactured from premium materials such as billet aluminum.
