I'm no expert on diesel installations (my previous boat was home built with a petrol engine modded to run on paraffin!) but now I've got one I'm trying to understand it. I believe the normal fuel line set up has a return from the common rail or high-pressure pump back to the filter and then to the tank, the reasoning being that the fuel injectors react more quickly than a pump can so it's better to have excess pump capacity and return the excess fuel than to have the pressure drop when the injectors want more. My boat doesn't have any of that, just a single fuel line via the filter to the pump. I guess that because it's an old engine (Perkins 100 series) without any fancy ECU set up the injectors just squirt what the pump sends. Could also be that it was originally a petrol engined cruiser and the diesel was fitted by a cowboy, so I'd like your opinions. Is it OK as it is?
