1954 gas sending unit

[Guy M.]

I'm thinking about installing the 56-62 sending unit in my replacement tank to see if it works better. Looks like a threaded connection on it to what?? Is that a vent that will need plugged? The one in there doesn't have that. Thanks for the help!

Did you try a 6v truck sender ?

Hi Chris, I did not. Wasn't sure that was an option. The one from CC reads twice as much as what's in there. My gauges are all rebuilt. Have you tried a truck sender, they the same?

6V repo senders are known to be defective.

I have a NOS truck sender but you can also used the 56-57 repo sender...and tank for that matter.

The truck sender I have and the 56-57 senders have a fuel outlet at the top of the tank. Of course the 53-55 tanks had the outlet at the bottom.

So what you do is cut the brass outlet tube fitting off the top. Then hammer the tube flat and single or double crimp it. That will close if off so gas fumes don't come out that tube. Or, if you have one the right size, just screw a brass plug into the outlet fitting to close it off.

When you install whatever sender you choose don't assume the float arm is bent correctly. Bend it so the float touches the bottom of your tank and the gauge just then reads empty. You have to have the sender wires connected and the ignition switch on. Then knowing the tank holds 16.4 gallons, add 4 gallons and check that you at 1/4 tank. Then add 8 more gallons and see if you are at 3/4. Since most senders are not accurate throughout the entire range, adjust the float arm to where it is accurate at the level you prefer. Personally I like to have accuracy at the lower end so I won't run out of fuel.

Once you are satisfied with the adjustment screw the sender to the tank and install the cover.
