Value? My Father-in-laws 1971 Cutlass Supreme Convertible

Maybe I’ll hook it up (outside of the tank) to the dash wire and see what it shows in the gauge before I install it.

I did the same thing and the gauge moved up and down with the float, but when installed with gas in the tank it still reads 2/3-3/4 full when 100% full and reads empty when it actually has 1/3-1/2 tank.

Since you mentioned the reading inaccuracy of the new sender, I checked the new and old sender side by side. You are correct: There is definitely a difference in the heights due to the bend of the float hangers. I adjusted the bends with a pliers so the new float hanger matches the old one. Hopefully it makes the reading more accurate this way.

Before and after (full and empty positions)

Success! Gas gauge reads correctly. This is the reading after I put in 8 gallons. Long day...especially when you have to wait all day for amazon to deliver the lock-ring and O-ring that were missing from the fuel tank sender assembly.

Love the bucket seats and no console.

My wife just got back from the In-Laws house. Lots of paperwork found. Has the original dealership owner's manual glove box folder with the original Window Sticker in it. Sold new at Tunmore Olds in Buffalo New York by salesman Dick Hudson. The folder has the original owner's name on it: Frank J. Gugliuzza. Found the second owner's NY inspection receipt from 1985 at 39,601 miles. Third owner NY inspection receipt with 57,000 miles from 1995. Third owner's Bill of sale to my Father in law's brother in 2000 (Fourth owner) and then my Father in law (5th owner) getting it in September of 2002 with 59,000 miles. So my Father In-Law put 40,000 miles on it in 23 years.

LOL. I tried googling the possible original owner's name "Frank J Gugliuzza." OMG there are dozens of them...and they all lived in upstate NY near Buffalo! It reminded me of the crazy 1984 movie Buckaroo Bonzai Across the 8th Dimension, where all the aliens have the same first name.
