Just gotta find the right setting. I definitly helps to know how much fuel is in your tank when you calibrate the gauge. | | | | | Joined: Apr 2006 Posts: 172 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2006 Posts: 172 | hm, i wonder how i adjust the gauge. i'm not sure of the brand or anything i should probably ask the guy i bought it from. thanks. | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | Patrick,
The electrical value of the sending unit and gauge must match.
I'm going to guess that a '63 has a common 90 ohm sending unit and I'll bet your gauge might too. See if the install instructions for your fuel gauge specify you install one of their senders too.
If everything is matched properly you can bend the float arm on the sending unit itself so the FULL-EMPTY readings are more accurate.
If this error came about after your new gauge was installed it might be a mis-match with the sending unit.
In my area, $20 dollars worth of gas would hardly move the needle at all...my old Silverado takes $88 clams to fill with a factory tank! Let us know how it turns out.
