I took a short piece of flex tube, 6mm fuel tube, and then interfaced
with a piece of copper tube, you could use 6mm aluminium, to route past
all the hot bits and then along the radiator ducts to rear.

a hole in the cowl below the pump and redux in a small tube stub, sanded
flush with the exterior. I then run silicone hose between the pump and
the tube. On the classic I figure any fuel from a blown diaphragm will
stream rearward along the outside of the cowl, hopefully missing the hot
bits - that's the theory anyway lol
