Fuel manifolds and distribution blocks are central components in multi-injector EFI systems where a single supply line must feed multiple injectors or fuel circuits simultaneously without pressure drop between individual feeds. In individual throttle body setups, large-displacement engines with multiple fuel rails, and nitrous systems where dedicated enrichment circuits run alongside the main fuel system, a properly sized fuel manifold maintains equal fuel pressure to every outlet regardless of demand variation. Billet aluminum construction is the standard for performance applications, offering the machinability needed for custom AN port configurations and the rigidity to resist fuel pressure spikes without expansion. Choosing the right manifold port count and inlet size for your flow demands ensures consistent fuel distribution at all RPM and load conditions. Popular Upgrades Top-selling fuel manifolds include Aeromotive billet distribution blocks in AN-8 and AN-10 inlets for high-...
