"Acquainted" is one way of putting it. You do not say if the fuel pump
is working. If it is, a rebuild may be unnecesary and may not even
solve your problem. Fuel leaks can creep about and make it difficult to
know where the origin is but I would start with the inlet and outlet
line. These connections depend on the olive seating well into the
pump. If there is a burr or foreign matter there, if the fuel line
extends too far past the olive or if the compression nut isn't tightened
far enough in -- the olive will not seat. The fuel bowl is also proe to
leaking on the tractor engine -- not sure if this would occur on a 6.
Could also be leaking around the diaphram but I have never had that
occur -- I think one or more of the screws would have to be very loose
for this to happen.
One trick for finding the leak point is to clean it up and get it dry --
then run the engine with a bit of brown paper towel (like you get at gas
stations) against the likely spots for the leak. The smallest drop will
be immediately evident on such a towel as a dark spot. FWIW -- I use
teflon tape on the threads of the compression nut not as a sealant but
to make it thread easier as it may need to crank down quite a bit to get
the olive to seal.
