4. First, make a note of how the wire connectors are attached to
each terminal on the microswitch, and then detach the wire
connectors.
NOTE:
It is always recommended to label and tag all wires, wire
connectors and harnesses prior to disconnecting them, so as to
correctly identify their connections/locations when reassembling.
Alternatively, you can photograph the wire connections prior to
disconnecting (for example, with your mobile phone).

4. Remove hex compression nut on the gas tube that connects to the
solenoid with a 9/16 inch wrench. If possible, simultaneously use a
1/2 inch wrench to hold the nut on the solenoid while removing the
gas tube (see Figure 46, page 38).
5. Then remove the compression nut at the other side of the gas
tube to detach it from the jet holder assembly. Be careful not to
bend the gas tube.
