Quicksilver fuel pipe
I'm aware this is a known issue to some but worth a reminder as our outboards, tanks and fuel lines age.
When I had the no-start (resulting in me finding carb jet blockage from gasket material) the other day on my Yamaha 15F the fuel line was something on my check list.
When I bought the 2003 Yamaha from a dealer last year he offered me a choice of used tanks. I chose my preferred Quicksilver 25l which came with its original fuel line and primer.
This silver Quicksilver fuel pipe can suffer delamination internally blocking connectors or filters so when changing to the Yamaha outboard end connector last year I cut off a short bit of pipe to check and it seemed fine.
But despite the problem being elsewhere this time thought I'd double check the pipe while I was at it and disconnected it from the primer in the middle of its length. As shown in the attached image I immediately saw significant delamination. The pipe was date stamped 2002.
New Yamaha OE line and primer on its way now.
