assembly is mounted on top of the tank and cannot be
removed for service without lowering the tank. The
upper filler neck assembly is routed through an opening
in the rear panel above the bumper and through the trunk
floor pan (fig. 33). The filler neck is not centered in the
rear panel but offset to the right to obtain the proper fill
rate.
The fuel pickup pipe is an integral part of the tank
meter unit^ located at the top front center of the tank. A
fine mesh screen is located at the bottom end of the fuel
pickup pipe to prevent the entrance of foreign material
into the fuel system.

lines extend from the fuel tank to the right side of the

to the carburetor.
Maintenance
CAUTION:
plete fuel
Always drain gasoline from corn-
including carburetor, fuel
pump and
fuel lines and fuel tank if the
vehicle is to be stored for any
eciable
length of time. This precaution will prevent
accumulation of gum formation and resultant
poor engine performance.
The fuel lines should occasionally be inspected for
leaks, kinks, or dents. If evidence of dirt is found in the
carburetor or fuel pump disassembly, the lines should be
disconnected and blown out. Check the fuel tank strainer
for damage or omission. Fuel lines are of 5/16" diameter
tubing for regular installation with beaded-type ends for
connections to hoses and flared ends for secure line
connections.
