Fuel Pump Hangers & In-Tank Pump Assemblies

Fuel Pump Hangers & In-Tank Pump Assemblies

Fuel pump hangers, also called pickup assemblies or pump hats, are the structural component that suspends the fuel pump inside the tank and positions the pickup tube at the correct depth for consistent fuel delivery under all vehicle attitudes including hard acceleration, braking, and cornering. In custom fuel cell builds, the hanger must be fabricated or selected to match the cell's depth and internal dimensions, with the pickup tube length and anti-surge baffle positioning designed around the vehicle's expected dynamic load conditions. Factory replacement hangers restore the OEM geometry and fuel level sender calibration when replacing a failed pump module, while performance hangers from Aeromotive and Holley allow custom positioning of high-flow pump bodies that are larger than the factory module housing. Getting the hanger geometry right eliminates the fuel starvation issues that appear during hard cornering or sustained high-speed running when poorly positioned pickups uncover momentarily.

Popular Upgrades

Top-selling fuel pump hangers include Aeromotive universal billet fuel cell hanger kits with adjustable pickup tube length for custom tank installations, Walbro complete hanger assemblies with pre-wired pump connectors for popular domestic car and truck platforms, and Holley tank-specific drop-in hanger kits for early Mustang, Camaro, and Chevelle restomod builds. For drag racing applications, Canton and Moroso fabricated billet hangers with dual-pickup anti-surge design maintain fuel supply to the pump during hard launches and under braking. Aeromotive Phantom stealth sump kits that mount to the floor of a standard fuel tank using a custom hanger are among the most popular high-flow in-tank solutions for street and track dual-purpose builds.

Performance and Handling

Anti-surge baffling built into or added around the pump hanger is the most effective way to prevent fuel starvation during cornering in tanks with large empty areas as fuel level drops below half. Trapping a small volume of fuel around the pump pickup using a check-valve-equipped surge pot welded to the tank floor ensures the pump always draws from a pool of fuel even if the main tank volume is briefly displaced away from the pickup. For road course and autocross applications, a well-designed hanger with a proper surge pot or foam baffling is as important as pump flow capacity for preventing lean-out conditions at low fuel levels during hard driving.

How long should my fuel pump pickup tube be in a custom fuel cell?

The pickup tube should position the pump inlet approximately 0.5 to 1 inch above the bottom of the fuel cell to avoid drawing tank sediment and debris while still accessing the lowest available fuel volume. For cells with a sloped or sumped floor, position the pickup at the lowest point of the sump to maximize usable fuel capacity. If running an anti-surge sump inside the cell, position the pickup tube within the sump walls at the sump floor level rather than at the main cell floor level.

Can I use a factory fuel pump hanger in a custom fuel cell build?

Factory pump hangers are designed to fit specific tank dimensions and flange openings, making them compatible with custom fuel cells only if the cell is built to match the factory flange diameter and depth. Universal billet hangers with adjustable pickup tube length from Aeromotive and Holley are the better choice for custom cell builds where depth varies and exact positioning is critical. Using a factory hanger in an oversized cell creates insufficient pickup depth, drawing air before the cell is fully empty and causing premature fuel starvation.
