A boss must be “welded” or “bolted on” and then machined for the injectors. Should you wish to do this yourself, we offer all the components and even the tooling (see Page #144 - TOOLING TO MACHINE FUEL RAILS AND INJECTOR MOUNTING). EFI injectors and fuel rails installed on dual 4-barrel manifold for big block Mopar INSTALLATION OF CONSTANT FLOW FUEL INJECTION Constant flow fuel metering - typically the nozzle has a 1/8” NPT thread. Most cast aluminum manifolds have runner walls thick enough that they can just be drilled and tapped for this size. However, most fabricated sheet aluminum manifold have runner walls too thin to be drilled and tapped. Provided there is no epoxy in the runners, a boss can be welded into place, then drilled and tapped. Mono valve throttle body with constant flow fuel metering VINTAGE HILBORN HEMI MANIFOLD CONVERTED FOR EFI Converts Hilborn 2 7/16” manifold (model: 426-C-8A) to electronic fuel injection. Billet aluminum plates bolt to existing ramtube 2-bolt pattern, accepts our combination billet aluminum EFI injector holder and ramtube adapter. The holders can be installed with the injector towards the center of the engine or out by the valve covers. Holders accept our extruded aluminum or stainless steel fuel rails. Allows the use of 2 3/8” inside diameter aluminum ramtubes which have a nominal outside diameter of 2.490”. Throttle position sensor is mounted on the previous barrel valve mounting pad in the center of the manifold using #7086 remote TPS mount (see Page #149). The remote TPS mount will be connected to the throttle shaft using a hex link bar.
