REPAIR PROCEDURES
The following procedures involve the replacement of the 90~ formed hose (connecting the electric fuel pump to the gauge unit fuel tube) with a straight
hose, and replacing the straight filter with a "T" filter. In addition to reworking vehicles with the vapor lock kits installed, any vapor lock kits or service
kits for gauges and fuel pumps must also be reworked if they carry the old part numbers.
This procedure applies to converting vapor lock packages to the updated packages. This same procedure also applies to reworking service gauge/pump
units to the updated service packages. Rework kit, PN 4075490, must be used.
1.
Locate gauge/pump unit, PN 4075448 or 4075449. If removal from gas tank is necessary, follow service manual procedure.
FOR THE ENTIRE REWORK PROCEDURE USE EXTREME CAUTION NOT TO BEND THE FLOAT ARM AND HINGE ASSEMBLY.

pump (Figure 1).
