Fuel sending units read WRONG time after time!

I better probably clarify a little though -

When I say it worked, it did....mostly. LOL

When I fill up the tank, it reads full.

When it says there is a half tank it was pretty close.

When it reads 1/4 tank, though, not so sure it perfect.

When it hits 1/4 tank, I can get 10.5 or so gallons onto the tank. I was working with the idea that my tank holds 14 gallons. That would be close.

Well, I recently came across info that says my tank is an 18 gallon tank. Not 100% sure that is true or not.

That throws off the calculations obviously if it is.

For whatever reason, once I get below 1/2 tank it is off as far as accuracy, but rather than telling me it has more gas than I have , it says I have less......I figure that is like a built in "reserve" for when my gauge says "get gas" but my brain says "lets just go a little further before stopping for gas"...LOL

But this was as close as it got after many tries adjusting the arm....adding the wire made a huge difference in accuracy.

Now, to make things interesting, I will be swapping in a new tank soon.....same sender.....will have to confirm that things are still about the same....LOL

I guess that little bit of unknown is what makes these cars fun! :glasses7:

FWIW - I did check the wiring between the tank and my gauge and it was fine as far as ohms.
