Size of fuel line on M-25 in a CD-31

Post by Capt Hook »

Can anyone tell me the size of the fuel line on an M-25 in a CD 31?

This past weekend my wife sniffed out a diesel leak which I traced to the return line to the tank. That was 1/4" ID.

The supply line is bigger but I can't find anything in the manuals that gives the size. I'd like to order the line ahead of time and not have to bleed the system twice, once to get size to order and then again when I make the swap.

And can anyone verify that all sections between the tank and the injection pump are the same size. They appear to be but just want to be sure before I start to dissect.
