Ratchet with 3” extension

Flat blade screwdriver

STEP 1

Position the heater on a stable workbench. The outer case consists of two halves.

Locate the 4 hex bolts (yellow rectangle) as shown in the pic below.

This is the case that you need to remove by undoing the 2.5mm hex head bolts. (red
circles) 22pcs total. DO NOT REMOVE THE 4 BOLTS IN THE YELLOW RECTANGLE.

STEP 2

With the 22 hex bolts now removed, gently remove the case from the main frame to allow you to reach in and disconnect the battery connection.

Once disconnected, you can put the case with the battery aside and out of the way.

STEP 3

Using the T25 Torx socket with ratchet and extension remove the fuel pump mounting bolt.

STEP 4

Remove the electric fuel pump plug using a small flat blade screwdriver to release the locking spring.

STEP 5

Refit the locking spring clip to the plug.

STEP 6
