My Westerbeke is Sucking Air - Help!

[skipmac]

Help. I can't keep fuel going into my Westerbeke.

Just bought the boat (and thinking about resurrecting the thread about POs and what they did). Assumed the fuel was old so ran it enough to get home and planned to deal with it asap. But before I could the engine starting choking down so shut off and changed both filters, primary Racor water sep (was full of crap) and the secondary on the engine. Filled both filters, bled a little and cranked up. Engine ran for about 2 mins and stopped. Checked and both filters were dry. Took fuel lines apart and blew backwards into the tank and got bubbling. Put system back together, refilled filters, bled a little more, cranked, same results. Checked lines for leaks, found one that was cracked on the end, cut back to good rubber and replaced (yes I plan to replace the whole thing as soon as I can get to the store to get more fuel line).

I've repeated this several times and every time both filters are emptied. The Racor is only empty in the top housing, the glass bowl stays full. I have cleared the line from the Racor all the way back to the tank and also checked the vent.

Any ideas what to try next?
