Hi, Can anyone give a little guidance please? I'd like to identify which are delivering fuel to the engine and which are returning to the tank in the engine bay. For example, there are 2 fuel pipes paired at the rear of the bay one placed above the other. Has anyone got knowledge of which is delivering fuel to the engine and which is returning to the tank?
Thanks in anticipation.
Rob

Thank you for the diagrams and the entertainment. I'll double check but I think the 203 layout appears schematically similar. Would the hose to the engine generally be bigger dia than the one back to the tank (the flow having reduced)?
Thanks again
