3) Install the fuse of fuel pump to main fuse box.
4) Start the engine.
5) Measure the fuel pressure after warming up the
engine.
Fuel pressure:
Standard: 338 — 348 kPa (3.4 — 3.5 kgf/cm2,
49 — 50.5 psi)
NOTE:
The fuel pressure gauge registers 10 to 20 kPa (0.1
to 0.2 kgf/cm2, 1 to 3 psi) higher than standard val-
ues during high-altitude operations.

29) Disconnect the fuel delivery hose and evapora-
tion hose.
(1) Disconnect the connector of fuel pipe by
pushing the ST in the direction of arrow.

(2) Remove the clamp, and disconnect the
evaporation hose from the pipe.
CAUTION:
•Collect fuel from the hose into container.
•Disconnect the hose with its end wrapped
with cloth to prevent fuel from splashing.
30) Support the engine with a lifting device and
wire ropes.
31) Support the transmission with a garage jack.
CAUTION:
Doing this is very important because the trans-
mission lowers for its own weight. This work is
also of great importance for facilitating reinstal-
lation.
CAUTION:
Before removing the engine away from trans-
mission, check to be sure no work has been
overlooked.
32) Separation of engine and transmission:
(1) Remove the starter. REMOVAL, Starter.>
(2) Remove the bolts which hold upper side of
transmission to engine.
33) Install the ST to converter case.

(1) Slightly raise the engine.
(2) Raise the transmission with garage jack.
(3) Move the engine horizontally until main shaft
is withdrawn from clutch cover.
(4) Slowly move the engine away from engine
compartment.
NOTE:
Be careful not to damage adjacent parts or body
panels with crank pulley, oil level gauge, etc.
