Auto Meter 1501 - Manual

CAUTION:
If working on a tank that contains fuel or fuel
vapors, use extreme caution. Carefully follow
these steps to minimize danger from explosive
fuel vapor.
Installation Procedure
(Tank must be empty, clean and free of fuel.)
FIGURE 1
1. Extinguish all cigarettes and remove open flames, hot material and anything else
that might ignite fuel or fuel vapor from area. Be sure there is adequate
ventilation in work area.
2. Remove ignition key and disconnect ground (-) cable from battery.
3. Drain fuel from tank and remove from area. Reinstall drain plug. Disconnect the
fuel line from the fuel tank. Remove the mounting straps or bolts which fasten the
fuel tank to the vehicle than remove tank.
4. Remove old sender and remove all remains of the gasket from the old sender
from the fuel tank. A clean surface is required for proper sealing of the new fuel
sender and neoprene/cork gasket. If excessive debris is found in the fuel tank,
flush with water and thoroughly dry the tank with forced air.
5. Auto Meter has two different styles of fuel sender. View the sender from the top
with the float arm extended perpendicular from the stem. See FIGURE 1 to
determine which sender you have. Type 1 (top) has top nuts off-center and the
float extends from one side of the float arm. Type 2 (bottom) has centered nuts
on top and the float is centered on the float arm.
6. If you have the Type 1 Fuel Sender refer to instructions 7-14. If you have Type 2
Fuel Sender refer to instructions 15-23 on the reverse side.
TYPE “1”
7. Measure tank depth where the new fuel sender will be installed. Refer then to
ADJUSTMENT TABLE 1 for correct lengths of float arm (Length “A”) and stem
(Length “B”). Adjust the length of the stem by loosening the adjusting screws.
Retighten the screws when the correct length is reached. Remove the float arm
from the assembly and cut to Length “A”. Reattach float arm to the float arm
connecter with set screw and locknut See FIGURE 2.
8. Slide the gasket over the float arm and sending unit to fit flat against the
underside of the mounting plate. Place the fuel sender in the fuel tank and align
the five holes in the sender flange with the holes in the fuel tank. The five
mounting holes are not equally spaced and will only line up in one angular
position. This allows repositioning of the float arm relative to the mounting holes
every 90°. If necessary to rotate the sending unit for your installation, loosen the
brass nut on the bottom of the mounting plate enough to allow the stem to rotate.
Make sure to rotate the stem in 90° increments to insure clearance of the float
arm with the tank wall.
9. Check for adequate clearance between float and fuel tank wall. (By holding fuel
level sender up along side of the fuel tank, you can better check for clearance of
vertical tank wall). If the tank wall interferes with the travel of the float arm,
loosen the stem mounting nut and rotate the stem to a position where the float will
clear the tank wall.
10. Place the fuel level sender back in the fuel tank and check for clearance between
the float and the bottom of the tank. The float can not touch the bottom of the
tank. If the float does touch the bottom of the tank, double check the tank depth,
float arm length and stem length. Make the appropriate adjustments to the
sender and recheck it.
11. Tighten all of the fuel sender ’s fasteners including the stem mounting nut, stem
adjustment screws, and the float arm set screw and locknut.
12. Install the fuel level sender and gasket in the tank using the five flange screws.
Leak test this area to ensure a proper seal. If unsure how to perform any of the
above or below procedures, or are unsure of electrical wiring connections, seek
the services of a qualified individual.
13 Reconnect the wire from the fuel level gauge to the sender terminal stud with the
nuts provided. If the fuel tank is not metal or if it is fastened to the vehicle with
only straps, a separate wire from one of the five flange screws to a good chassis
ground is necessary.
14. Tighten all the sender ’s fasteners and reinstall the fuel tank in the vehicle.
Reattach the fuel line to the tank and tighten the drain plug.
