When you fill your tank and see the fluid level in the sight glass on the gauge line up with the index marks on outer ring of the gauge, is the "F" supposed to be centered with it's own index marks on that visable line of fuel? I ask this to know if that is supposed to be correct then when the opposit happens (you get down to the zero mark you can count on being out of fuel.

The gas gauge just needs to be calibrated. Instructions are posted here in the archives, and in the Service Bulletins.

Brent, I tried to search archive under " fuel gauge calibration" as well as "gas gauge calibration " before I posted and came up with nothing that answered my question. So should the visible line of fuel be up and over the gauge ring index mark and when the gauge reads "F" centered on the gauge ring index?

Mark, if I understand the question, YES.

When the gauge reads empty you should have a gallon or so left.

The answer above, quoted again here, is the best answer:

Bend the end of a coat hanger wire into a small hook and gently pull the float arm up until the float touches the top of the tank inside. Have an assistant look at the gauge. It should read with the F centered on the center of the lens. If not, bend arm inside gas tank up or down to get the F centered.

Once you have done this, the Empty and the other readings are automatically correct.

I always worried more about how much gas is left once I get close to E. When I had my tank boiled & sealed, I also replaced the gauge and it took 5 gallons before the gauge moved. So I don't worry when it gets close to E. At least until I get around to calibrating it.

That is what I needed to read. I have the fuel gauge assembly parts and have been waiting for low fuel and time. Thanks.

I don't worry about being out of gas until I don't see any movement of the dial. It bobs some until it is out of gas.

Don't put up with that. Easy to fix, I'd rather it was working right!

Remember, when on cars with fender mounted fillers, we'd shake the car sideways, violently & quickly "listen" at the filler for sloshing sounds

Re-read post #10.
It is more important than you think, however you have your gauge set up.

If the gauge stops bouncing, then the float is on the dry bottom of the tank and you are gonna very quickly be out of gas.

When my gauge stops bouncing, I need to be close to a gas station for I have seven miles remaining.

If your in doubt of where you run out just drain all the gas out and see what it takes to move the gauge. That's what I've done before.

eagle · 08-12-2014, 08:37 AM

How about just run it until it stops and then you'll know. I call it calibrating myself. In my A, when it is on E and sits still, I will run out of gas in just a couple miles if its flat ground. I know this because I've done it. Its fine, you just better take it seriously when it says empty, it means it. I have another vehicle that will run for 75 miles after the "low fuel" light comes on. It irritates me because I know it doesn't mean it.
