Ford vs Chevy Build-up

Here you go Rich. Copied straight from Aeromotives website.

Unlike a standard or “dead-head” carburetor regulator, which controls pressure between itself and the carburetor by stopping flow, the bypass regulator controls pressure between itself and the pump by bypassing flow. The optimum EFI regulator location is after the fuel rail(s) when possible. All pump flow, minus engine consumption, must always run to the regulator, wherever it is. Putting it after the fuel rail means all fuel must run through the fuel rail, and over the injector inlet, at all times. This ensures full flow is available to the injector in any instant. Most Aeromotive EFI regulators have two inlet ports, one on each side, and one bypass port, on the bottom. Either inlet may be used with a single fuel rail engine, both inlets with dual fuel rail engines. Any unused inlet ports must be blocked with the appropriate port plug. The ideal flow-path is: out of the fuel pump, into one end of the rail; out the other end of the rail, into the regulator side port(s); out the regulator bottom (return) port, back to the top of the tank. Dual rail applications should employ a Y-block to split the supply line before entering the rails, then individual lines are run from the opposite end of each rail into each inlet port on the regulator.
