been blasting around the med most of this summer and the boat has been perfect (well nearly). yesterday just as we were nearly at our destination discovered that port engine was burning @ 10% more than the other. odd, but nearly there and no other symptoms. then I get a low fuel pressure warning alarm on the starboard engine. which had been using less fuel on the flow meters but the fuel tank level was less than expected. Slowed to idle and stuck head in engine bay and there is diesel everywhere! Diesel is spraying with some vigour out of the side of starboard engine.

Anyway shut down engine go into the harbour (Villa Joyosa if anyone knows it, pretty little town just south of Benidorm-not pretty) and tie up. explain to marineros that we a have a problem can we stay for a few hours (I hope). Get everyone off the boat as it stinks and is possible dangerous as the engine bay liners are full of the stuff. Pump out into containers and clean up the worst then examine the engine. there is a flexible braided hose from the engine filter that goes into the cylinder head and it has a split in it @ 1/2" long. Fetch it off and have a rummage in the big box of bits to see what I can cobble up and lo and behold there is a spare! the previous owner it turns out had replaced the port one at some point and had the sense to buy two. There is a God thinks I as I merrily (and rather smelly - covered in diesel by now) bolt it all back together, quick bleed, jobs done.

so if you have a D9 have a look at the fuel filter pipes - if its steel braided rubber from filter to cylinder head might be worth getting new ones as the design of the replacements is different. the new ones are rubber material but wrapped in what looks like a clear loose fitting plastic, which at first glance looks like packing material but its not it protects the external hose surface.
 
just about 7 years old - I suspect volvo have have done a mod at some point as the pipe is very close to the engine breathers. cleaned engine bay but then later as we left the harbour that the bilge pump came on as we went up onto the plane. it ran for about 7 - 8 mins. - I estimate from the fuel gauge @ 100 litres of Repsols finest has gone into the drink. got back to Torrevieja @ 11/2 hours later and boat is pretty smelly down stairs. lift up floor panels in bedrooms and find @ gallon of diesel settled in the lowest part of the boat. spent this morning pumping out and flushing with @ a gallon of fairy liquid to emulsify the remains. smells all clean now but i suspect I will need to do this a few more times.
 
Sounds pretty scary, especially as you were very lucky not to have the diesel spray onto the exhaust system which could've caused a serious fire......so pleased that you managed to fix the problem with only the diesel spill to clear up.
