Subject: Re: OP switch behind intake manifold by joeld on 2018/4/3 3:12:13 The oil pressure switch in regards to the pump running is for a back-up system only. When the engine starts after the initial "pressure build" the pump stays on and pumping. Any unused fuel is returned via the fuel return line from fuel rail and fuel pressure regulator. Joel |
