Those of you who were at Carlisle remember -- perhaps? -- that I went the whole weekend on a single tank of fuel? No? Truth is, in addition to adding 7.5 quarts of oil, I also fueled up twice.
Stupid floats.
So. There I was, minding my own business in the shop when suddenly, out of nowhere, my fuel tank sending unit appeared in my hand. Then, as if by magic, my screwdriver made a bunch of circles and gyrations the sending unit came apart.
Then, again as if by magic, the little float guy fell out of the tube into my other hand, revealing itself to have been built by a nimrod. A coupe seconds on the old belt sander ... and it floated freely up and down the tube like it was supposed to from the plant.
Lessons learned: take crap apart before you install it, take off the rough edges and put it back together and test it. Full range was 0-90 ohms, just like it was advertised to read.
BTW, if you do get a sending unit to go into a JAZ cell, for use with an AutoMeter gauge, there's a series of pickups and a magnetic strip up one side of a waferboard, and the other side is baby's butt smooth. The magnet that's supposed to be inside the float may come loose. Use a steel .001 feeler gauge and taco the magnet into it, trim appropriately and wedge it back into the float.
Presto-chango; no more float problems.
Thought y'all'd like to know. Next stop, tank straps. The old ones have been removed to let the tank breathe a little and relax the dimple out of it.
I'm driving the car anyway, 'cuz I'm a little off.
WOO-HOO!

I had one of those slidy-cork-thingies-in-a-tube gas gauge senders - came from my donor '69 Beetle sedan. Weirdest thing I'd seen since my family's Snow Mobile days back in the 60's, and the very first thing to get pitched (along with the rest of the rusty tank it was hiding in).

Went and got one of the non-slidy-cork-thingies-in-a-tube versions, which looks just like a "normal", good, American gas sender - float on an arm and nothing to bind. Messed with it a little to get the top and bottom limits to be more-or-less in line with full and reserve and then messed with it again to get the damn gasket to stop leaking (ended up making a new gasket from an inner tube) and it's been ok ever since.

The things you have to go through just to have a general idea (more like a suggestion) of when you're gonna run out of "Go-Juice".
