Happen to take a glance at the fuel line assembly. The plastic ends have become brittle and small pieces (around the ball) have cracked off.

Adding this to my PM list . . .

Once it begins to leak air into the fuel, the carburetor will get starved and stall out the engine. Was on a trip one time when it happened to me - I wrapped it with some teflon tape that got me through, but I needed to replace the fitting asap!

I had somewhat similar issue a few years ago with the quick disconnect from the hose outlet to engine inlet. Looking at the face of the connector, it had what I would call micro-cracks. Replaced the fitting.

Darn these things are expensive! $48 for an OEM version (Yamaha)

I may start disconnecting the engine side of the hose and stowing it in the fuel locker to protect it from UV. Of course I'll probaly just wear out the connector sooner

Storing the hose in the locker does not ensure the connector will not develop micro-cracks because I always disconect my fitting and store the hose and gas tank in the locker. Mueller and at least one other company sell replacement fuel connectors for most outboard models. I bought a replacement for my Honda fuel hose connector from Mueller and I believe it was something like $15 or less. So...the OEM Honda conncetor developed micro-cracks and the Mueller replacement has a cheapy metal flex plate instead of a real spring type connection but it works. I already had to replace one of the mueller conncetors because the flex plate kept coming off the connector or would hang up. But when I then bought two addl replacements from Mueller, I have found that if I just press on the outer edge of the flex plate they use in place of the spring that was on the Honda connector, the flex plate seems to work okay. I have had no micro-cracks form on the Mueller connector and still working with one of the two I bought. The connector has been working okay for 2 years now. Not exactly a long term assessment report but 2 years ...so far, so good.

To lessen the chances of a problem with fuel line connectors, I eliminated the tank side connector by replacing the tank fitting with a barbed fitting which the fuel line hose is directly clamped.

This happened 2 years ago, when the Mercury OEM fuel line was 4 years old...apparently, there is a liner within the hose designed to prevent leakage of fumes through the hose. Well, the liner itself was vulnerable to ethanol - it eroded and then began to disintegrate so much so the carb needed a rebuild...I replaced the line at that time and plan to do so again...
