Foam
..
Years ago BLMC made a car called the 1100. Nothing special
a decent little
runabout. As ever the accountants made the engineers sign it off before it
was really ready.
About 5 years later, quite a long time in the life of some of BLMC?s
offerings, 1100s started rotting out at the top of the rear rhs wheel arch.
Why? Well
.the very earliest purchasers noticed a buzz/vibration coming
from the back rhs at certain speeds.
Solution
..while car was being assembled, cram a cube of stiff foam between
the two panels and no more ?sympathetic vibration?. (I think that?s the
name?)
5 years later
..the foam is a wet cube of mud and salt and it rusts a hole
right through from the inside.
Don?t use foam.

Don?t use foam. It will rust out the tank and floor as it will absorb and
hold water.

My new fuel tank in the BJ8 has similar problems in installation. First of
all, I noticed that the old tank installation allowed road splash water to
enter the boot because the toward the forward end is tilted up to be able to
screw into the fuel fitting and sponge rubber only touches the tank on the
rear end of the tank. My idea was to use additional foam tape on the
forward end of the tank and silicone caulking to seal the opening. Also,
the tank is as loose in the straps so I used block of wood wedge to hold it
firm temporarily. So I hope the group can describe how to install a new tank
in and old car as allowing road water to enter the boot sounds illogical. My
new tank is temporarily installed.
