This is the most complete of Radium's plumbing kits, because the Prostar family spans both return style and returnless fuel systems and the kit has to cover each. It includes a fuel pulse damper to replace the original, a fuel feed adapter with an SAE quick connect that mounts on either the left or the right depending on the machine, an 8AN FPR adapter for older UTVs that carry a rail mounted fuel pressure regulator, and an 8AN ORB plug. You use either the plug or the FPR adapter, not both, depending on which fuel system the machine has. The damper's vacuum port is tapped #10-32 and a plug is supplied for it, since these Prostar engines do not need a vacuum reference.
