Maintenance Manual
3.4.7) Pressure connecting lines (only on 914 Series)
See Figs. 73-37 and 73-38.
The pressure connecting lines are of essential importance for safe
operation of the engine.
See also 73-00-00 sec. 2 and the correspond-
ing Maintenance Manual (Line Maintenance) for the respective engine
type, 912 or 914 Series.
Check all lines and T-fittings for damage (mechanical, thermal, etc.)
and leakage.
■
CAUTION: All lines are secured with clamps. Check them for
safety reasons.
If the lines have been detached or replaced, connect them correctly:
- hose nipple (2) to the T-fitting (3)
- T-fitting (3) to the fuel pressure regulator (4)
- T-fitting (3) to the condensation trap (5) (on older engine configura-
tions)
- condensation trap (5) to the airbox pressure sensor (on older engine
configurations)
- hose nipple (6) to solenoid valve (7) ((towards 2-pin electric
connector (8))
◆
NOTE: On newer engines the solenoid valve (7) is mounted on
the airbox (1). See 76-00-00 sec. 3.1.2.9.
- hose nipple (9) to solenoid valve (7) ((towards electric connector (8)
on the opposite side))
- solenoid valve (7) (top connection) to T-fitting (10)
- T-fitting (10) to float chamber venting of carburetor 1/3
- T-fitting (10) to float chamber venting of carburetor 2/4
Secure all lines with clamps 8 (11).
An exception are the 3 lines on the solenoid valve which, due to the
shape of the valve, must be secured with clamps 6.8 (12).
The lines to the float chamber venting must be fixed to the fuel lines with
tie wraps (13). Do not constrict!
