Fuel question!

[EThirty318i]

I'm in the process of a 318i> m20 swap. the motor and tranny are in, everything is pretty much hooked up... however, what fuel lines go to what? there seems to be two canisters (filters) for the fuel? not sure what hoses go where. help asap would be best, gotta have this car drivable by friday for the VIR rowlex series race

Point bothe hoses into a jug and jumper the fuel pump relay. The one that fuel comes out of goes to the fuel rail and the other goes to the FPR.

Okay thanks! And the fpr that's on the front aide of the fuel rail is the return line correct?

The FPR is front of the engine, yes, and is the starting point to return back to your fuel tank.

Okay and as for the canister with the two openings... What's the other hole used/ connected to it?

[jlevie]

The cannister with the two hose fittings is the the charcoal cannister and is part of the evaporative control system. One fitting goes to a hose that connects to one of the hard lines that run under the car and the other connects to the evap control valve that hangs from the bottom of the throttle body.

[scrowner]

Yeah. There are 3 lines running from the fuel tank to the front of the car. Supply, return, and the charcoal canister setup that runs from the throttle body to the canister and then back to the expansion tank of the car.
