hey people. i can see 2 lines running to the Fuel injectors, i know one is the fuel return line, and one is the fuel line running to the injectors.
they both seem to be going to the same place pretty much.
lcan somebody explain tp me which is the fuel line and which is the return line?

kinda confused

fuel line has a fuel filter on it, both run from the tank all the way to the rail.

fuel line runs from tank to the rail, return line runs from the regulator to the tank.
