gas tank sending unit
#5
If your going to check the sending unit (i.e. its removed from the tank) look for approx. zero to 3 ohms in the empty position and somewhere between 150to 165 ohms from empty to full.
FYI
Yellow terminal is the empty and gray terminal is full.
You can find the same two wires under the dash to check continuity. That gest you past the tank connection, body connection, and instrument connector.
The guage is more complicated of a test.
Remove battery prior to testing any of this stuff.

I just went through all that. I have a 1960 super 88. Fusick had the best price for sending units. The problem I had was the "sock" filter...
I bought mine through a chevy supplier. http://www.lategreatchevy.com/produc...dept%5Fid=1272
The sending unit is on top of your gas tank. I wasn't getting a reading on my fuel gauge so, I got the sending unit. (USA Auto Parts0 for $129.00) Fusick had the same unit for $69.00!
I dropped the tank (9 gallons of gas, premium still in it) took it to a shop to have it blasted, some shops still can do the "renue" process, they did something callled rattling, a process of shaking beads around to dislodge the chuncks of varnish, etc. Then, the spray an inhibitor.
At Late Great Chevy, be sure to check your size. 5/16 or 3/8
good luck.

I just got one of these for my Custom Cruiser. The gas gauge doesn't go below 1/4 tank. Not a big deal but I have to take the tank off to fix some corroded spots anyhow so figured I might as well change out the sending unit too! Was only $35 from Rock Auto...good price.
