Stewart Warner 385C-F Details

What brand of gauge will you use?
This Stewart Warner brand fuel sender is compatible with all Stewart Warner and Classic Instruments fuel gauges.

How deep is your tank?
Measure the depth of your tank where the fuel sender arm will be located. Choose the sender with an operating range which includes that dimension.

Right or Left-swing arm?
Most fuel gauge senders attach with a 5-screw pattern. Two of these screws are farther apart than the other three. Position yourself such that the 2 wider-spaced holes are closest to your chest; a right side sender will have the arm (or "float") extending to your right, and a left side sender will have the arm extending to your left. This only matters when replacing an existing sender. A first-time installation can use either one, just drill the mounting holes accordingly.

OHM
The OEMs used several different resistance ranges for fuel level indication over the years. However, some of the aftermarket gauge manufacturers follow the common Stewart Warner values (240 ohm empty, 33 ohm full). The gauges and senders that we carry (385 & 391’s) use these standard Stewart Warner values.

SW fuel gage and sender problem

After buying and installing the above SW set I found it would show about 1/8 tank of fuel when the sender was at the very bottom of the float travel. I ordered second sender and ended up with the same problem. I am told the problem can be corrected by using a resister in the fuel gage line to the gage. I have not tried the resister yet not knowing what value resister to use.

Used this sender in my 1934 ford Victoria and it worked great! The instructions were super simple and install was a cake walk. Just make sure you have a good ground wire.

Although the car isn't assembled yet, I "bench" assembled it to make sure it worked properly and it did because having a tank full of gas isn't the time to determine there is a problem...plus it helped me ascertain that the fuel gauge was also working properly.

Would Recommend

Great product and I would defiantly buy it again if needed

It's a little bit different from the old school and the new school but I can program it to the Dakota dash and it'll work just great
