[quote=ruderunner]Theory on why senders read full during a dry test vs actual use.
We're adjusting the senders and assuming the float will reach the top of the tank.
We're forgetting about air space above the fuel and the fact that the float won't touch the top of the tank in operation.
If someone is in this process, try setting the float for an inch gap from the top of the tank. Why do you believe there is air space at the top of the tank? IF the filler neck on say a 68-70 Charger is full of fuel, how could there be an air space ? Whether the neck is full or not, there's still going to be air pockets in the tank. Even the vent lines aren't completely against the top of the tank. Either way, the test is simple enough to try.

"Why do you believe there is air space at the top of the tank? IF the filler neck on say a 68-70 Charger is full of fuel, how could there be an air space ?" i have screwed up filling up my charger till the fuel ran all over the quarter, and out the vent line [which dumps into the frame rail] making a real mess. i don't think there was any air that time. [sure stayed on full for long time.] however, that was tons of years ago, and i'm super careful these days filling it up. also, the mess was during the time i had the original tank and sender in it. I've had nothing but problems filling older cars with gas and the spill over. I don't know if it's in the design of newer pump nozzles or what, but now I put my ear down and listen for it getting full and stop manually.
Facts are stubborn things.

After weeks of messing with this I ended up buying a new Auto Meter fuel gauge and Auto Meter fuel bridge to try out (pic). Couldn't get the fuel bridge to work as it should so I hooked the gauge up directly to my sender. The gauge now reads the sender but it reads backwards, full when empty and empty when full. At least now I know when it's empty or full just have to remember it's backwards. I can live with that.

At least now I know when it's empty or full just have to remember it's backwards. I can live with that. Not sure how that's wired but typically a DC circuit will indicate backwards if the polarity is reversed. So you might want to double check the wiring Yeah, that's what I was thinking, already tried that, same problem. The Auto Meter instructions say if the gauge reads backwards switching wires won't fix, need to buy a sender that's compatible with their gauge. I'm on my 3rd sender, I'll just live with what I have now. Tired of dropping the tank for this. Plus no one can seem to build a sender compatible for Mopar gauges, how in the world do we find a sender that will fit in an A body Mopar and be compatible with Auto Meter gauge? Good luck finding one of those, probably not even made.

I went through quite a circle jerk with them several years back on a VERY expensive set of programmable digital gauges in a customers car. they said they no longer have engineering as it is all done outside. I did what one is not supposed to and changed 3 things at the same time. I don't know to this day what fixed the issue we were having as it magically just started working. After losing 60+ hours on the problem I wasn't going to backtrack and try to identify the root cause. Still have a bunch of components that they kept sending ( throw parts at it) They are not the company they once were I just did a quick scan on the instructions and it should work I'll repeat, They are not the company they once were

okay, there are 3 prongs on the gauge; sender, ignition and ground, what wires do I switch? The instruction clearly state; swapping wires will not solve the problem.
