1. Insure that the fuel cell
is
not connected to the wiring
harness, and that the lift pump
is
connected.
2. Attach
Snap On MT337B, OTC
7211
or equivalent fuel
pressure gauge set to the Schrader valve on fuel cell.
A
CAUTION:
Follow
manufacturer's
instructions
for
safe
use
of
the
gauge
sets
to
purge
a
high-pressure
fuel
system.
3. While holding the stop switch in the
(prime)
depressed
position, purge the air from the fuel cell. The fuel cell
is
purged when no air bubbles are visible escaping from the
drain line attached to the
Schrader valve. Pressure should
typically be 3-4 psi.
4. Remove the pressure gauge set from the fuel cell and
connect it to the
Schrader valve on the throttle body.
5. Connect the fuel cell to the wiring harness.
6.
Open the valve on the fuel pressure gauge purge line. Do
not prime the system without the fuel gauge purge valve
open or air can be forced back into the fuel cell.
If
this
happens, repeat steps
1,
2,
and 3 to remove the trapped
air from the fuel cell.
7. Repeat step 3, this time purging the air completely from
the throttle body. The pressure should be
40 psi in the
throttle body after purging the system.
