VDO Fuel Sending Unit for 1961-67 VW Tank

You can bend the sender arm to adjust for reading full.

Thank you!  Is this possible with the stock sender? If so, where is the bend made and what am I trying to change?

thanks again,

Tom

The sender pictured should look like the one you have. To make it read full when full, hold the lid part oriented as it would be on the tank, and bend the float arm so the float goes down an inch or two. That way, when the float is at its highest point, with fuel full, the arm points higher, and that should make the needle on your gauge point higher.

This adjustment is trial and error, but a wise old builder once advised me thus:

Bend the arm, install the sender into an empty tank with two screws, leaving the screw holes on either side of the arm open. Loop a bit of string or mechanic's wire into the tank through the open holes and use the ends to move the float arm up and down. Attach the wires and turn on the key. When you get the float touching the top of the tank, gauge should read full. Drop it to the bottom, should get empty. Pull the sender and bend the arm to get it as close as you can. Shouldn't take more than two or three tries.

Perfect, thanks so much for the explanation Will adjust this weekend and report back with the results… 🙏
