Watch the sock to tube connection on these aftermarket senders. In 8 years mine was completely loose. And I noticed a brand new one had glue on the connection. Can’t remember if mine did originally.
The sock connection is stepped inside. It fits 5/16 and 1/2”. Not sure if the OE sock is like that.
Recently I had some rubber flake debris in the carb and filter. It would clog the float. I’d blow it out and then car would run fine until it did it again. I narrowed down to my sending unit rubber line (8 yrs old).
When I pulled sending unit to check things there wasn’t a sock on it. I have a wireless Depstech brand mini probe camera. I snaked it down the filler tube and I saw the sock was loose in the tank.
After an intense 2-man game of “Operation” we fished it out.
The sock fit so loose if you tilted the sending unit downward, the sock would slide off.
We put a little nipple flare in the end of the pickup tube and its tight and snaps on.
First pic is unit “as found” without the flare on end of tube. I also had the ‘71 style vent nipple finally welded shut.
