Fuel Return Line - None Fitted

[cpedw]

I'm not an expert and I've never understood why diesel engines have fuel return - why not just send enough fuel?

But all the engines that I have known have returned fuel via a pipe connecting all the injetors together. I think this is the vital part that should be connected to the fuel return line.

I look aftre a boat with a Petkins 4-236. It too has no return pipe; however, the return goes to a spare input on the CAV fuel filter.
Seems to work OK.
