Diesel leak in lower compartment

[mgayle4]

Hi, folks. My first post here.

Recently my mother bought a '96 42' WLWB. There has always been a bit
of diesel odor in the lower compartment. Lately there has been a film
of diesel on the overhead panels of the cargo area, as well as a
diesel sheen over everything in the compartment.

I will have to admit that I took a "diesel bath" when I refilled the
tank after our last outing in the coach, but I cannot find any way
that the overflow could have gotten into the cargo area. Also, we
cleaned the entire compartment with hot water and soap, only to have
the diesel re-accumulate.

The diesel collects in the channel along the inner walls that surround
the LP tank and main fuel tank, and drains back and drips onto the
ground at the back of the cargo area on both sides.

I have removed the upper panel above the sliding cargo platform and
everything up there was dry, as well as everything inside the LP tank
access panel. I cannot find any leak on the diesel hoses/tubing
running to the AquaHot unit either.

I am at wit's end with trying to find the source of this diesel. I
will add that the fuel tank is full. It was filled to the "bathing
level" (hehe) less than 10 miles from my house.

Any insights or suggestions will be very much appreciated.
