There doesn’t appear to be enough room to pre-install the fuel sending unit in the tank, prior to lifting and twisting the tank into place. It would be so much easier if the sending unit were installed over on the bench, rather then trying to squeeze the new o-ring (sending unit to tank seal) after the tank is up under the car.
We’ve ran into a couple issues trying to get this refreshed tank installed, and before we go at it again, I wanted to get some input on this subject. There just doesn’t seem to be enough room to get the sending tube up and over the cross-member if we do things the easy way.
Hi Ed,
I believe you'll find that the tank can typically be installed with the sending unit in place.
But I think you'll also find that it's pretty straight forward to put the unit in place with the tank already in the car.

Ed,
I normally instll the sending unininthe tank rpior to me installignth feul tank.
Depending onth e tube onteh sending unint..sometimes it may conflict witheh rear crossmemeber that hold s up the rar portion ofth fuelt ank...butnot so much that oyu can not rotoate th tank inot place. I ahv doenit countless times.
And the sending unit CAN be installed with the fuel tank in place but it can be a but challenging getting it in.
I also verify that when I get the sending unit in the tank...before I lock it in place...I visually inspect the filter sock that is attached to the end of the tube of the sending unit and make sure it is where it needs to be in relation to the bottom of the fuel tank. Sometimes I need to teak on this tube to get it where I like it to be so there is not a lot of excessive stress on the filter sock and the pick up for the fuel is close to the bottom of the tank.
On my 69 I have had no problem removing and replacing the sending unit with the tank in the car. It may be worth spending the few dollars for the tool to lock the ring in place.
Hi Ed,
I agree with MW that having the 'tool' is a good idea. (Probably a BETTER idea then being a 'tool'!)
Also, take a close look at the mount and 'tabs' on the tank and on the lock ring too before you start to install the sender.
That way you'll be able to understand what's being accomplished when the lock ring is rotated and how the gasket seals the tank.

Great pic’s, thx
We did make a mental note of the notches, and determine how the ring needs to be installed.
Since we don’t have the “special tool” and it’s not available anywhere that we can find, we’ll have to depress the new seal as best as we can...
Based on these responses, I think we’ll install the sending unit on the bench first, and see how
it goes. Worst case, we un-install the sending unit, and approach it the other way.
Ed,
Can you post a photo of your new sending unit. The reason I am asking you to do so is so you can do something to if BEFORE you install it.
ALSO...be aware of the amount of tension is being applied when you spin the lock for your sending unit. if it seems to easily slide in place an not press the sending unit against the rubber gasket..you might need to use the original lock or do some modifications to it. I have also found some of the large 'O' ring gaskets for the sending unit be actually a bit thicker which thus allows the lock to work better.
Also...to save oyu a lot of grief. When oyu get the sending unit installed. You can add gas to the fuel tank and get it in there enough to cover the area where the sending unit goes. You can see this through the filler neck area. Let it sit and make sure it is sealed up.
