fuel line routing - pics needed

[Svenn Ryen]

Hi

The fuel lines on my C15A are cut off and replaced with rubber hoses. At the switch what i believe is metric copper tubing for connecting these hoses. My fuel filter was also by-passed

From what I make out tubing should have OD 5/16 and be of steel?

The picture in the manual does not show correct routing from what I make out, only the set up.

All info on fuel line routing from tanks to switch, switch to filter, filter to pump and pump to carb apriciated.

Pictures, sizes, hose lengths, thread/fitting sizes would be great.
thanks

Svenn
