supply hoses (103) and attach a bushing to each
end of the third air hose. See the Parts Drawing on

7. Connect one air hose between the feed pump and
the 1/2 npt(f) air manifold on the side of the Foam-
Cat sprayer pump stand. Repeat for the other feed
pump.

the main air supply line to the air valve.

WARNING
The special air line fitting (J) and coupler (N) are
designed to prevent accidentally coupling an
unregulated air supply hose to the container.
Unregulated air can overpressurize the container and
cause it to rupture, resulting in serious bodily injury
and property damage. If the coupler and fitting ever
needs to be replaced use only original Graco parts.
Never substitute a different type of coupler and fitting!
