1.4 Length of the fuel hoses
Depending on the combination of
connector/carburetor, view the following fuel hose
lengths below.

The hoses (a) and (b) can be cut to length from the
3.1 x 5.7 mm bulk stock hose.
Always inspect for fuel leaks after servicing the fuel

. When using press fluid OH 723, apply press
fluid to the ends of the hose and connectors
prior to installation.
Notes regarding press fluid OH 723
Press fluid OH 723 produces a lubricant film to aid
in assembly. The lubricant evaporates after a short
time allowing for a tight fit.
Never use fuel, oil or grease as a lubricant. Fuel, oil
and grease does not evaporate and may allow the
hose to slip from the connector.
