As you know I'm a noob when it comes to diesesed engines, can someone explain what these are?
Is it just the diesel equivalent of a petrol return pipe (to the tank)? Or something else?
I've read they can leak, which lets air into the system, so they don't simply return unused fuel or it wouldn't matter how much air is in there.
I've also read that the fuel pressure in the line is important.
I'm confused, what are they for?
