FUEL GAUGE READS APPROX. 1/8 TANK WHEN EMPTY-BEND FLOAT ARM

SUBJECT: FUEL GAUGE READS APPROXIMATELY 1/8 TANK WHEN EMPTY - BEND FUEL SENDER FLOAT ARM

MODELS/YEARS: 1991-92 BRAVADA

Some 1991-92 Bravadas may exhibit inaccurate fuel gauge readings. If this condition is encountered, the fuel gauge will read 1/8 of a tank on the gauge when the tank is empty. This is due to the fuel sender float contacting the bottom of the fuel tank. The condition can be corrected by bending the fuel sender's float arm. The float arm must be bent so that the float arm angle is approximately 87 degrees. Figure 1 demonstrates the fuel sender before and after the bending procedure. When correctly bent, the float arm angle will match the template printed on page 4 of in this bulletin.

SERVICE PROCEDURE

Important: Before servicing the fuel sender, proper diagnosis of the fuel gauge must be performed according to "Diagnosis Of The Fuel Gage" Section 8A-8A-9 in the 1992 Bravada Service Manual.

1. Remove the fuel tank as outlined in the "Fuel Tank Replacement" section, page 6E2-C2-19 & 20, in the 1992 Bravada Service Manual.

2. Remove the fuel sender assembly as outlined in the "Fuel Pump Removal" section, page 6E2-C2-17, in the 1992 Bravada Bravada Service Manual.

3. Using the template provided, check the float arm angle (Figures 2 and 3). If the angle does not match the template, grasp the fuel sender with pliers as shown in Figure 4 and bend the float arm until it matches the template (angle equals 87 degrees).

Note: Damage to the gauge readout will occur if the sender is not held properly during the bending procedure.

4. Install the fuel sender assembly as outlined in the "Fuel Pump Install" section, page 6E2-C2-17 in the 1992 Bravada Service Manual.

Important: The fuel sender seal ring (P/N 3893116, currently available from GMSPO) must be replaced.

5. Install the fuel tank as outlined in the "Fuel Tank Replacement" section, 6E2-C2-20, in the 1992 Bravada Service Manual.

Important: Tighten the upper tank straps last, and torque to 5.5 - 8.0 N.m. (4.0 - 6.0 lbs. ft.)
