Onan
Maintenance After
verifying that fuel was in fact getting to the carburetor on
the Onan, disassembly was required to find out what was
stopped up. Further analysis determined that the fuel line
between the fuel pump and the carburetor bowl was
deteriorating, with the lining of the hose breaking up and
sloughing off. The following photographs are virtually
self-explanatory, if you understand the general problem, and
virtually impossible to explain if you don't!
Enjoy!
With the input "el"
removed, you can clearly see the "trash" on top of the
needle valve seat.

The fix in place. As a
side comment, I still ended up having to replace the fuel
pump, shown here on the left, before I got complete
resolution of the problem!
