INSTALLATION SERVICE POINTS
Installation of the fuel gauge unit & pump assembly and the fuel gauge unit & pipe assembly requires great care to prevent the units from being misaligned. Misalignment will cause the float arm to contact the cup reservoir or other interior surface of the tank, hampering its movement and resulting in inaccurate fuel gauge reading or improper operation of the low fuel warning light.
Four major points should be observed when installing the fuel gauge units into the fuel tank.
1. Ensure that the fuel gauge unit & pump assembly and the fuel gauge unit & pipe assembly are aligned properly before installing them in the tank. These assemblies must not and cannot be rotated after they are in the tank.
2. Ensure that the two assemblies are aligned properly after installation.
3. After installing the two assemblies in the tank and before torquing the nuts, look to see that the rubber gasket did not roll under when the unit was pushed into position. The edge of the gasket must be flush with the pump mounting flange, evenly all the way around. If it is not even, pull out the unit, reinsert it more carefully, and again check to insure that the gasket seals properly.
4. Do not allow either assembly to rotate out of position, and watch that the special tool does not damage any of the piping.
ALIGNMENT MARKS
Alignment marks on the fuel gauge unit & pump assembly and fuel gauge unit & pipe assembly could be confused with spot welds, etc. The alignment marks are two depressed dots stamped into the metal top of the unit. They are about 1/8 inch in diameter and about 1/8 inch apart. The marks on the fuel gauge unit & pipe assembly are near the white electrical connector. On the fuel gauge unit & pump assembly, the marks are near the fuel return pipe nipple. It may be necessary to clean the unit in order to distinguish these marks from other stamped dimples and spot welds.
The tank has two alignment marks. These are molded into the tank surface. Each is a single line about 3/8 inch long pointing toward the center of the mounting hole.
