That's what I thought at first, but the feed hole into the filter head is right at the bottom as its on its side, so a good 90% of what was is the fiter has run back to the sump over the 8 months its been standing. Yesterday after the run to the show I switched off the isolation tap at the bottom of the frame and took the rubber feed pipe off with a drain tin underneath, it was bone dry this morning when I checked, so happy the isolation valve is not leaking.
