Note: Cut hose to fit.
3.5
Secure the other end of the molded hose to the
existing tee/pressure switch assembly using an
existing hose clamp.
3.6
Secure the molded hose (276206) to the
tee/pressure switch assembly using an existing

Note: Cut hose to fit.
3.7
Route the other end of the molded hose to the left
hole in the sound shield's customer connection
panel. Secure the hose with an existing hose
clamp.
3.8
Secure the hose (X-312-51) to the heat exchanger
end cap. Secure the hose using a hose clamp
(X-426-12). See Figure 7.
3.9
Route the hose from the heat exchanger end cap to
the right hole in the sound shield's customer
connection panel. Secure the hose with a hose
clamp (X-426-12).
Note: Because of the variety of possible
installations, this kit does not include
hoses to connect to the siphon break. See
Figure 5 for an ID-size hose selection.
Use coolant hoses (SAE 20R1, class B or
equivalent) and hoses suitable for marine
use. Use corrosion-resistant or stainless
steel hose clamps on all fittings.

other rigid structure. Keep the siphon break reed
valve in a vertical position.
Note: Correct functioning of the reed valve
requires
Locate the top of the siphon break (reed
valve) away from possible accumulated
dirt and other contaminants.
Note: To prevent water leakage on the generator
set, do not mount the siphon break over
the generator set.
3.14 Connect
the
clear
(GM34883) to the siphon break cap using a hose
clamp (X-426-9) to secure. Route the tubing to a
convenient location. This allows the seawater to
drip into the bilge and not on the generator set.
3.15 Siphon break mounting varies with each
application. Generally, use brass or stainless
steel screws and mount the siphon break using
the mounting tabs.
