In my opinion an easier solution is to fill it
from inside of the Westy through the top of the
tank!  This is what I do.

fittings that make the

nipple that fits into 1/4

pushed about 6 inches of

brass nipple and trimmed the

the male fitting on the end of

inch pipe thread (brass)

female pipe thread bell reducer

> 3 - 3/8 inch male pipe threads by 1/4 inch (I
think) tubing nipple (brass)
> 4 - 6 inches 1/4 inch I.D. by 3/8 inch O.D.

> To make the filler even easier to use you can
buy a small plastic valve that

garden section). It has female

hose and male hose threads on

brass fittings listed above.

B_T problem.
