To the list I forgot to say that after it has run dry and the engine has shut down and you turn the T handle on the racor you can hear & feel that there is a vacuum being released as the top of the filter comes loose. My fuel tanks have always been slow to fill but the vents lines are clear and I do get a little over flow from them when the tanks are topped off. This problem just started last weekend and I can only go for about 30 min. at 1400 RPM before the stbd. engines shut down. Tomorrow I will try to run it in the slip at about 1000 RPM and see if it will suck dry. Any ideas will be gladly received. Bruce Creswell M/V Soon Come Bellaire, Tx.
