One thing I found helpful is to lightly grease the metal-on-metal camming surfaces of the locking ring/gas tank fitting. This area can bind-up a bit during assembly even when using the proper tool.

GM did indeed use engine oil and Quanta recommends it as well when replacing the sending unit. Here's a previous thread on the subject for the non-believers - https://www.corvetteforum.com/forums...ding-unit.html
Repo. seals work perfectly IF they are installed correctly.
JohnZ states - "In the plant, we kept the fat rubber O-ring seals in a tray of motor oil for several hours before installing them; the requirement to do that is in the Assembly Manual, in the "Lubricants" section that decodes the lube symbol on the sheet that shows the installation."

I agree both O-rings can be made to work......maybe there is more than one repro vendor because mine was not sealing; even after 1/2 day in a coffee cup of oil...

Good to know - too bad they didn't include that in the GM shop manuals for the poor field tech ....

JohnZ has been instructing us about the o-rings and "the bucket of engine oil" for about 15 years now..........ever since I have been on the forum. But it is good to repeat for all.

What can I say ?
I followed the shop manual procedure using good parts and was successful; as did prob 20 million mechanics over the years...
I think that about covers it...

Yes..........there is more than one vendor for the gaskets. The best one I have seen recently is made/sold (last few years) by OEM Reproductions, and is now the one sold by many of our parts suppliers. The ring and the cam lock supplied with my Quanta tank 5 years ago were both not very good, and were immediately thrown away.

Did you mean OER reproductions? I'm not finding much under OEM Reproductions.

Dr Rebuild site has how to identify this GM o-ring by the embossed logo. Here is the link: https://shop.docrebuild.com/1963-197...825206NOS.aspx
I knew this but could not immediately remember the correct logo without going to the garage. Then I remembered the Dr has it on his webpage.
Enjoy.

This will get interesting. I have now seem NOS prices for the O-ring from $3 to $25.
Thanks again, I really appreciate it!
