Return PolicyHow 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.

You need to ntify world that your sending unit fits perfectly into old chevy gas tanks. You have to replace gas guage and sending units. resistance on sending unit is different. You can use the old float. Mine is a "84 p/u with dual tanks. I just luck out in finding it. Thanks I've told my friends what to do if theirs goes out.

I bought Stewart Warner gauges years ago when they were based in Lancaster, Pa. Recently, got back on the project and discovered I did not have the fuel tank sender. It had an unusual resistance range (ohms) according to the SW instructions. Luckily Speedway Motors had the exact sender I needed to fit in my custom made tank. Testing on a 12 volt battery the tracking was smooth on the gas gauge on the dash and the tracking was linear. Would hate to run out of gas cruising with my wife in a Sunday afternoon!

I have a 1957 VW beetle that does not have a gas gauge. Could I use this and would this work and if so can I purchase a universal gauge to go with it? Also the tank has a shallow end first near the fuel cap and then it goes down to the deep end on the other side. Thank you
