My '63 had a ground wire terminal apparently welded to the pickup / sensor unit. My replacement doesn't have the terminal. Is it necessary? If so, how have others attached a terminal to the pickup / sensor? Thanks!

Re: Mid Year Gas Tank Ground
I would have one welded on. Inadequate grounding is a major cause of electrical problems in Corvettes, and the area of the gas tank is the last place you'd want to develop a spark across to ground. Are you certain you have the right sending unit? -
Re: Mid Year Gas Tank Ground
Bought it from what I consider to be a reputable vendor of Corvette stuff. Has anyone else gotten one that had a ground on it? I might consider drilling and tapping a hole in one of the corners of the tank (outside the weld) and running my own ground wire to the frame.Comment

Re: Mid Year Gas Tank Ground
I can't get at my sender on the car at the moment, but figure 23 on page 12-13 of the 63 Corvette Shop manual clearly shows 2 round connectors (they should be marked "S" and "I") and a flat spade ground connector on the base of the sender. The text also refers to fig. 23, saying to connect the "black & white stripe lead to ground terminal". Having said that, I do have a sender on the shelf that I think was purported to be a midyear sender when I purchased it at a swap meet a few years back (unfortunately I didn't tag it as such)... it does NOT have a ground terminal. If I were to use that sender, I would have a spade connector added to the base.
Also, you might check the sender you have with an ohmmeter (across the round posts) to ensure that resistance varies smoothly from 0 ohms to about 90 ohms as the arm is moved through it's full travel.Comment
