Edd;

 

I also have an M35B, and I've dealt with two diesel leaks over the 10 years
I've had the boat.

 

The first leak was in a flare fitting in a copper fuel return line that work
hardened due to vibration. The flare cracked, and had a small leak. Moral 1:
Copper fuel lines suck. Use rubber. Moral 2: Always put a spiral coil in a
copper line adjacent to any flare fittings to absorb the vibration.

 

The second leak was a pinhole in the bottom of the stainless fuel tank where
it sat on a wooden platform. Moral, put in rubber pads to space the tank
from the platform so there is no crevice corrosion form trapped moisture.

 

As Bill Coleman suggested, put a bit of paper towel around each fitting. You
will find any leak pretty quickly. And if the engines does not shut down
while running because of air in the line, look especially hard at the fuel
return connections.

Subject: Stus-List Smelling Fuel After The Engine Runs

 

Listers,

 

            I'm getting a pretty strong diesel smell after I run the engine
for a bit, so I'm worried I may have a leak in one of the hoses. When I run
my bilge pump, I do see some slight rainbow coloring in the water. 

 

            Before I go checking everything out this weekend and disconnect
any hose clamps, is there anything that I should be careful about (letting
air into the fuel lines, etc.)?

 

          Would appreciate any advice from anyone -- especially from those
who have experienced and fixed a similar problem. 

 

 

          All the best,

 

          Edd
