Ok in my 1971 corvette assm manual there is a reference to 3724851 tape at a location inside the car & behind a console panel.
I will remove it later today, take a photo, and report my findings.

I should have my hands on 3M Temflex Friction  1755 by next week

ALL, I got a Roll of the 3M 1755 & it is more like the tape used to serve the rear light harness in the trunk, cloth fiber -vs- crepe

still looking,,,,,,,,,

I could not find the place behind the console where the tape was indicated to be located.
I will try another location...

Jim, to clarify are you looking for a crepe-style tape or fiber-cloth?

Given the photos of the back side of the tape, It really looks like a paper backing of some kind rather than cloth, I was disappointed in the 3M 1755 which looks just like the AMK & others cloth rubber tape used on a 67-68 rear taillight harness.

A few of the previous photos make the tape appear to be -(I think they are Lloyds) crepe paper and appear to be over 1/2" maybe 9/16-5/8" wide, and then a couple appear like the thin plastic tape with fiber backing and appear to be under 1/2" -maybe 3/8 -7/16 wide ?
Am I making the wrong judgement as far as sizes and composition of tape go?

Here are offerings from AMK that include a 5/8" wide black masking tape. Part# B-11664 is described as "Commonly used to attach GM wiring harnesses to body structure or tie loose wires". Could this be what you're looking for?

It's been a marathon trying to attached the photos. My apologies if I've got it wrong.

The photo of my sender seems show a crepe / masking tape style tape much like in Reply #21.

This is a picture of of the top of my tank during restoration, 28K never out of the car. The tape in the picture while not shown in the AM, was in my opinion the same as used on the fuel line and ground strap rubber cover. No pictures of that part of the tank. It was thicker than regular masking tape. I used 1" wide "Freezer Masking Tape" to replace it.

There was also the number 26 printed on the tank which was probably a mill mark for the steel.

Just took a second look at the picture. The wire from the fuel sending unit is over the tape, there was "no stick" left on the tape. The glue from the anti-squeak strap was the only thing holding the tape on the tank.

I decided to use a crepe style tape based on the photo evidence of most of the original tape remnants. I narrowed the 2" width tape I had to about 3/4" and transferred the rubber sleeve from the original sending unit onto an NOS sender I was able to source.

Lloyd,
You may have not noticed that the grounding terminal on the replacement fuel pickup/sending unit is different than the assembly line installed one. Squared and brass VS steel and round
I swapped it out on one of the cars I did because I couldn't find a correct replacement.

I annealed the original with a torch then pried open the tabs and put it on the replacement sender. FWIW If you don't anneal the metal the tabs will break off when trying to "recrimp" it.
Here is a photo of your original posted earlier.

James, yes I did notice. I removed and restored the original sending unit ground strap terminal for that reason however I made the mistake of cutting the wire short when I removed it from the old sender so the only way to replace it would be to splice it in-line. I was thinking of soldering it then using shrink tube followed by tucking it under the crepe tape. Based on your constructive "terminal shaming" I may just do that!
