Fuel line clog

[Wmiii]

While we were heading South today, our engine stopped. After troubleshooting and a tow to a nearby marina, we discovered a blockage in the fuel line. It was where the line leaves the tank and was a glob of 'Stuff' that completely stopped the fuel flow.
It is now cleared, but I wonder when/if the next blockage will occure and what to do to prevent it.
Thanks,

Diesel?? Based on what you described, you will need to have your fuel & tanks 'polished'. Likely have more 'stuff' (algea) in the bottom of the tank(s). Any additives you add to rid the algea will also cause more to break free from bottom or baffles in the tanks. Get it done correctly with a 'fuel tank polisher' and his cetrifugal pump. They need to access the tank through an inspection port to properly agitate the stuff off the bottom, walls and baffles and then cycle all the fuel through the pump. Works really great. After your tanks are clean, use an additive to keep the algea on the down low and keep the tanks full of diesel.

Yes, get the fuel polished and the tank cleaned. If you do not you will have this problem again, probably when you're bouncing around in the ocean. Fix it now.

I had my fuel polished a couple of years ago, but nothing done to the tank. I guess that is my next option when I get somewhere to get it done.
Thanks,

I have been aboard many boats 1) haven't been moved in a while and 2)who swear they don't have a dirty tank problem. Then, when the tanks get 'agitated' in a sea way, low and behold, the raycor is fouled.. boats!

Yes, unfortunately, the tank surfaces ars the culprit. Just cycling the fuel will not get the stuff attached to the bottom/walls/baffles. After a while, the attached stuff sloughs off...
