Fuel Tank: Clogged?

[agilmore]

My Tartan 27 diesel fuel tank will not feed fuel to my Westerbeke 11A diesel. I tried sucking on the fuel line hose, nothing. This problem started after the engine was sitting for about 7 weeks.

I tried blowing into the hose and some bubbles gurgled for a bit, then stopped and I couldn't get any more air into the tank by blowing.

I removed the vent line, nothing changed.

I suppose the next step is remove the tank and pull the fittings to inspect?

Also, the tank is metal, probably .050 inch. Is there any sort of fitting I can put in the bottom to drain off water and sludge? I am thinking about a fitting that I can just drill a hole and attach without welding. The tank is galvanized.

Thanks,
