Mounting Ring Fuel Pump Module 4.75in S/S

The Mounting Ring Fuel Pump Module 4.75in S/S by Aeromotive is a precision-engineered stainless steel component designed for serious fuel system builders and high-performance engine tuners. This mounting ring serves as the foundation for integrating fuel pump modules into custom fuel tanks, whether you're building a street rod, race car, or modified daily driver. The 4.75-inch diameter ring accommodates Aeromotive's modular fuel pump assemblies, allowing you to consolidate pump, regulator, and filtration into a single sealed tank-top assembly that eliminates external plumbing complexity.

Constructed from stainless steel, this mounting ring resists corrosion and fuel degradation far better than stamped steel alternatives, ensuring long-term reliability in both alcohol and gasoline fuel environments. The 4.75-inch bore diameter is engineered to create a secure interference fit with Aeromotive's modular pump module cartridges, while the threaded or snap-ring design (depending on your tank configuration) allows tool-free or minimal-tool installation. The compact footprint—8 x 1.75 x 8 inches—maximizes internal tank space while maintaining structural integrity and proper fuel sump geometry for consistent pump priming and performance across acceleration, braking, and cornering loads.

This ring is ideal for fabricators building custom fuel tanks from aluminum or steel, as well as for those retrofitting modern fuel delivery into classic vehicles or converting carbureted platforms to EFI. It integrates seamlessly with Aeromotive's complete modular fuel system offerings, providing the mechanical foundation that allows you to spec pump output, regulator type, and filter micron rating independently. Installation requires tank removal and careful bore preparation; precision fitment is critical to maintain the seal integrity that keeps fuel vapors contained and prevents siphoning during prolonged storage or towing.
