Jon, I also purchased an anti wet sump valve, but with the amount of suck it took to lift the spring loaded ball of the seat I could not bring myself to use it, any takers? but I could not trust myself to turn a manual tap on every time I start, and it only takes once, I fitted a concealed, discreet locking device to my Dave Hills stand and am surprised how many times that I have tried to push it off the stand with the lock engaged, for me, what are the chances of forgetting the tap. By far the best solution was devised by Marcus Bowden, a very simple but cleverly engineered petrol tap that also has a linkage to a tap fitted to the oil feed pipe, that is on Old Harry I think, you cannot turn the fuel on without also turning the oil on, idiot proof, just what I need.
