SUBJECT: NEW STYLE HOSE #309363 - CRANKCASE TO FUEL PUMP
FOR ALL V-50 AND V-75 ENGINES.
A redesigned hose of improved construction is presently being used on
75 H.P. engines to connect the fuel pump with the engine crankcase.
This new hose has been strengthened by an internal lamination of rayon
cords and will prevent hose rupture due to engine backfire.
The new hose is easily identified by
its smaller diameter and by the herr-
ing bone pattern on its exterior sur-
face.
To install (on all 1961 and later V-75
H.P. engines) order -
1 - #309363 Hose
2 - #309523 Clamp (required to
accommodate smaller diameter
hose).
1 - #309740 Spring
NOTE: #309740 spring must be installed
over the hose, covering the sharp
180° bend near the fuel pump, to
prevent it from collapsing in
this area. See illustration in
Figure 1.
All parts mentioned in this bulletin are now available from your Parts
Distributor at the list price shown in the current Johnson Master Price
List. Order only from your Parts Distributor - the standard parts dis-
count applies.
