Help Me Understand The Stock FPR
#2
I miscorrected the post thinking I understood before sinking 20hrs of work into creating the perfect set of adapters and rubber tubes to match the required bends and trying to fix leak after leak but this things going in the garbage. I don't have a way to attach to the fat golden end which I thought was the return/dump port the other way it just seems to pressurize the line and spray out one or some of the clamps. **** this bull**** I lost so many braincells to gas fumes

It's a pretty simple design. The pump wants to move a certain volume of fuel when it is on, if the engine isn't consuming that volume, the pressure generated by the pump builds up until the relief valve opens and allows some fuel to escape. The tube on the side just directs the excess flow back below the liquid level in the tank. This is likely because it generates less vapors in the tank and is quieter.
