The Bump 0 Posted April 10, 2011 Share Posted April 10, 2011 Does anyone know a good marine diesel mechanic who can look at a wee motor in Gulf Harbour Marina? I have a consistant pesky little fuel leak and darned if I can find it - the people who normally service it cant find it - so time for a fresh pair of eyes I'm thinking...advice anyone?

wheels 543 Posted April 10, 2011 Share Posted April 10, 2011 Where exactly do you find the leaking fuel?? Link to post Share on other sites
The Bump 0 Posted April 10, 2011 Author Share Posted April 10, 2011 been a pesky amount - about half a cup after motoring in flat water for about 2 hours. We had a fuel leak through the top of the tank where the sender unit is fixed - got that fixed (we think) - yet we have kept the tank low (about a third full) - and have not been out in rough conditions or leant the boat over - so it cant be spilling from the top of the tank.... The area around the tank looks dry and clear - the fuel collects in the RHS only and sits in an area trapped by the floor boards. The engine looks ok - cant see an area where it may be coming from - but certain it is not the sender now.....and cant see anywhere else on fuel lines etc where it may be leaking from....need fresh eyes I think!

John B 106 Posted April 10, 2011 Share Posted April 10, 2011 It might be the tank. As experienced by a mate last year, stainless tanks rot from the inside out where any residual water accumulates and sits. That manifested for him as a pinhole seep at the tank lowpoint and then as a full blown 'find the bilges full of diesel' nuisance ,fortunately a few weeks before the christmas cruise. That would have been a full on disaster for his holiday if it had happened while he was out there. The best tool for finding that sort of thing ( and worked in this installation)without removal is to get a digital camera in there under the thing and take a bunch of photos until you find it.

rigger 47 Posted April 10, 2011 Share Posted April 10, 2011 another way of finding small leaks is to clean the area well removing oil and fuel then apply an oil paste - it changes colour when it comes in contact with oil / fuel. Link to post Share on other sites
smithy09 50 Posted April 11, 2011 Share Posted April 11, 2011 Nothing worse than the bilges stinking of diesel. Sympathies there! Link to post Share on other sites
Guest mental outlook Posted April 11, 2011 Share Posted April 11, 2011 It could be the bottom of the tank, that is what happened to my Y88. It had a tiny crack on one of the bottom corners of the tank emptying the whole lot on the bilge over a 48 hour period (after a beating coming back from the Barrier). Once out it also showed signs of corrosion where it sat on the foam and glass bearers also so we welded some solid stainless bar to the bottom of it so it sat on that and not the tank. May be of help. Link to post Share on other sites
