- position of z4 axis of the fuel manifold:
◆ NOTE: Dimensions always from point of reference (P).
- return line to tank (5):
outside dia. ..... 7 mm (.28 in.)
slip-on length: . max. 17 mm (.67 in.)
- pressure gauge connection (6):
outside dia. ..... 6 mm (.24 in.)
slip-on length: . max. 17 mm (.67 in.)
- fuel pressure switch connection (9):
thread .............. M10
thread length:.. max. 9 mm (.35 in.)
Tightening torque: 15 Nm (135 in.lb) and Loctite 221.
■ CAUTION: At loosening or tightening of the banjo bolt (7) (tighten-
ing torque 10 Nm = 90 in.lb.) support the fuel manifold
appropriately.
◆ NOTE: The connection nipple (5) is furnished with an orifice
(8) (0,35 mm = 0.014 in.) essential for operation of the
fuel system.
If the pressure gauge connection (6) is not used and a
hose nipple (10) installed, the banjo bolt assy. (11)
marked with a colour dot or marked "FUEL" is fur-
nished with an orifice (12) (0,35 mm = 0.014 in.). This
is essential for operation of the fuel system as it
prevents a loss in fuel pressure.
