Not sure where you are going here, but tvat sender is easily repaired. The how to here on fabo details the procedure.

As for aftermarket senders...

If the sender is not tuned to the guage AND the tank it will never be accurite.

If your aftermarket sender is tuned to your aftermarket guage it should read fairly accuritely. Only the shape of the tank is the variable and after the first 5 gallons or so the tank is fairly liner.

Pretty Simple.

Everyone bashes the aftermarket sender stuff as not being accurate! They also come up with this list of reasons, or thoughts as to why!

I say you need to look a bit Further! Match new with old and ohh! Wire resistance and a tired A-body v-reg fuel gauge + everything to do with these 50+ year old cars must be taken into consideration!

I am giving a shout out to Charger Specialties gauges, M&H harnesses and more as they work well with either! One of the smart things I have done, to offset the Dumb!

We have all read the Values of resistance oh so many times! yet this simple problem keeps arising for some! It is is more than a check at the sender. It must be the same all the way to the gauge terminal at a minimum.
