14.5) Notes on checking of fuel pressure
See Fig. 52.
There is no standard connection provided to measure the full pressure. For general
observation and at engine troubles fuel pressure readings would be helpful.
A feasible connection would be an additional hose nipple 4/6 (1) joined to the fuel line
(2).
- remove banjo bolt M10x1x19. Fit additional hose nipple (with integrated orifice) (1)
and 2 sealing rings (3) by use of a longer banjo bolt (4) M10x1x30.
Tightening torque of the banjo bolt: 15 Nm (133 in.lb).
■ CAUTION: At tightening of the fuel lines (2) support the specific line, to prevent any
internal stresses.
◆ NOTE: The Fig. 34 shows the additional ring hose nipple connected to fuel line
of carburetor 1/3 (1). This ring hose nipple may be also fitted on the fuel
line 2/4 (7), but not on the outlet (5) and inlet (6).
All the necessary items are available as spare parts.
