governor barrel.
CAUTION
Remove spring dowel which secures barrel in
fuel pump, before attempting to remove
governor barrel. To pull spring dowel, insert

whether standard size barrel (fig. B-17)
can be used. Minimum 0.001 inch interference fit is
required.
(4) To locate a new governor barrel in the housing,
scribe a center line on barrel and housing, lining up the
fuel passages to prevent fuel flow restriction (fig. 3-85).
(5) Heat housing in oven to 300 degrees Fahrenheit.

method.

lubricant.
