Extended Length Bracket & Tube Kit

The Holley Extended Length Bracket & Tube Kit (part number 12-161) is a bolt-on fuel pump bracket assembly engineered for deep-tank applications in the 12–15 inch range. This retrofit kit pairs a precision-engineered mounting bracket with a matched fuel delivery tube, designed to integrate Holley in-tank fuel pumps into tanks where standard bracket depth falls short. The kit addresses a common challenge in fuel system retrofits: maintaining proper pump submersion and flow integrity when tank geometry requires extended reach.

The extended bracket geometry ensures the pump inlet stays submerged throughout vehicle operation, critical for preventing cavitation and vapor lock—issues that compromise fuel pressure consistency and engine performance. The included tube is sized to match the bracket extension, eliminating guesswork in component pairing and ensuring flow path continuity from tank floor to pump inlet. At 0.67 lbs, the complete assembly is lightweight without sacrificing structural rigidity. Installation is straightforward bolt-on design, compatible with existing Holley in-tank fuel pump platforms, making this kit ideal for fuel system upgrades where OEM brackets lack adequate depth.

This bracket and tube kit serves builders and technicians working on fuel system installations requiring precise tank-to-pump geometry. It's particularly valuable in custom fuel cell installations, aftermarket tank swaps, or restoration projects where deep-tank configurations are specified. The kit eliminates the trial-and-error process of sourcing mismatched components and delivers a matched pair engineered to function as a system. Holley's reputation in fuel delivery systems backs the precision machining and materials used in this bracket assembly.
