F36 Fuel leak

[ArthurWood]

We've been looking at a very well kept 1998 F36 w/2x330 Cummins, but noticed fuel in the bilge. Owner had it cleaned up and Cummins bloke came today, a week later, to try to find origin of fuel. Bilge was clean after week's standing. After ~3hrs running today, about a cup of fuel is in the bilge again. Cummins bloke says it's not coming from the engines or filters and left. Any (constructive) thoughts from you learned lot as to where to look next for the leak?

check the filler and vent hoses etc
also if both fuel returns go to one tank and drawing off from another

Hmm that was a quick response. Thanks Scottie and y'all. I'll let you know what happens. Now back to the chicken I've just grilled out on the patio. Had to turn on the AC to eat dinner in comfort but you didn't want to know that, did you!

Missing Link was the F36 (model year 1998) and it was fine except it was one of a few F36s that had its fuel panel reverse-plumbed; a not uncommon mistake on various motorboats (always worth checking).

Fuel leak was on the original MBM F37 Calm Voyager. It was an early F37 (model year 2000) with plastic tanks (discontinued some time back); quite a good idea in some respects because well baffled, no sharp edge welds to fail, no corrosion worries and you could visually check levels. Sadly the inspection hatches supplied on our boat were not man enough for the job and had to be replaced. After that one of the tanks then developed a further leak. Then sod's law kicked in big time and someone damaged a fuel pipe when Sealine decided to swap tanks out for conventional ones -- it was one of those occasions when you knew that the likelyhood of success would be in precise inversion to the effort expended by all parties. Got it cracked in the end.

Current (model year 2002) Calm Voyager F37 is fine -- actually on the limited hours I have had on her she seems the best of the three in terms of general togetherness although still have fond memories of Missing Link which looked after me very well.
