Gas Tank Sump Kit

The Competition Engineering Gas Tank Sump Kit (C4040) is a weld-on fuel tank sump designed for custom fuel system installations and performance vehicle builds. This steel sump assembly provides reliable fuel pickup and settling capacity for vehicles requiring upgraded or custom fuel tank configurations, making it essential for serious engine swaps, race builds, and custom hot rod projects where OEM fuel systems are no longer suitable.

The sump measures 11 inches long by 7.375 inches wide by 3 inches tall and features two 3/8-inch NPT female bungs for fuel line connections and system integration. The natural steel construction weighs 2.6 pounds and is designed as a universal fit for custom fabrication work. The NPT female threaded bungs accommodate standard fuel system fittings, allowing builders to configure fuel pickup lines, return lines, and drain provisions according to their specific application requirements. Weld-on construction requires integration into a custom or existing fuel tank during fabrication or tank modification.

This product is intended for experienced builders, fabricators, and automotive enthusiasts undertaking complete fuel system redesigns. Common applications include LS engine swaps, vintage hot rod fuel system upgrades, race car builds, and off-road vehicle installations where fuel surge tanks or modified pickup geometry is required. The sump's internal geometry helps prevent fuel starvation during acceleration and cornering by maintaining consistent fuel availability to the pump intake. Proper installation requires welding skills and knowledge of fuel system safety requirements, including grounding and proper vent line configuration to prevent pressure buildup.

Competition Engineering manufactures quality fuel system components recognized in the automotive fabrication and hot rod communities. This weld-on sump is a functional building block rather than a complete plug-and-play system, suited for builders who understand fuel tank modification, welding, and fuel system plumbing. Buyers should verify compatibility with their specific tank design and ensure all work meets safety and regulatory standards for their jurisdiction before finalizing installation.
