Been reading up on the problematic OEM lift pump & aftermarket solutions. I have to say I'm a bit confused as to why the aftermarket pumps have a relief valve. I can understand that there needs to be a return to the tank from the lift pump to dump the air that has been removed from the fuel. But doesn't the OEM fuel system have a pressure relief valve that maintains supply pressure, and bleeds the excess into the fuel return line at the injection pump? Also doesn't the excess fuel used to cool the IP? If the pressure relief valve on the LP opens up, what happens to the required extra flow to the IP? Is the OEM pressure relief/return system overwhelmed by the aftermarket pump's flow so it cannot control pressure? So to compensate the aftermarket LP pressure relief is set at a slightly higher value than the OEM system's pressure relief valve, acting like a secondary pressure relief? That set-up may allow all the flow the OEM system can handle but prevent an over pressurization of the IP - just guessing here. I saw a YouTube video Michael made showing a slow flow of fuel running into a bucket out of an open hose. Does that represent the 70% of supply flowing back to the tank? Thanks for your time,Joe in St Louis
