Product Description
GRANATELLI HIGH-PERFORMANCE FUEL SYSTEMS
BUILD A CLEANER, MORE COMPACT TWIN-PUMP FUEL SYSTEM.
The Granatelli Motor Sports GM821B Billet Twin Fuel Pump Manifold & Bracket Kit provides a professional solution for mounting two compatible external fuel pumps into one organized assembly.
Featuring billet aluminum construction, integrated inlet and outlet manifolds, and multiple ORB-style ports, the GM821B helps simplify fuel-line routing while providing a clean, compact foundation for high-performance EFI, turbocharged, supercharged and racing fuel systems.
FUEL SYSTEM PACKAGING THAT MATTERS
Why Use a Dedicated Twin-Pump Manifold & Bracket?
High-output EFI and forced-induction engines can demand significantly more fuel volume than a single external pump can provide. The GM821B consolidates two compatible external fuel pumps into one compact mounting and manifold assembly, helping simplify fuel plumbing and eliminate the need for separate pump clamps and distribution blocks.
