Fuel tank sending unit question
Just took the tank out of my '68 a few weeks ago. I was planning on re-using the original sending unit (that worked fine). It's stamped "90 ohms" on the steel cover that's over the float hinge so I assume it's original.
When I took it out, I noticed that the float when up and down effortlessly. When I changed the sock on the sender, the float would move up and down as I turned the send over and back. When I looked at it yesterday, I noticed that the float now has some resistance to it. It kind of needs to be "nudged" by hand to move. Almost as if it has a few sticking points during it's length of travel as it's moving up and down.
As it's been out of the fuel tank for a few weeks, could it have tightened up a little for some reason - maybe because it's not actually in the gas? Will it loosen back up once it's immersed in fuel again?
Finally, I can probably spray some lubricant inside the steel cover that's over the hinge. It doesn't look like it's totally sealed as the seems around the cover have slight gaps to them. Would that be a good idea or no? I would think that's where the resistor is housed and I'm no sure if I'd be doing any damage to it giving it a few squirts of something like WD-40.
