Default Gas Gauge Will Not Go Up To Full

I have a 1997 Camry. The last two times I filled the gas tank up at the
gas station, I filled it up to the point that the the pump clicks and
then pit in a little more gas. However, for the first time in the car's
life, the gas gauge did not go up to full. It stopped right below the
full line. Any thoughts on why it would do that?

There is a worn spot on the Sending Unit. This happens when the tank is
kept at a certain level for a LONG time. If you're like me, you have kept
the tank full since owning the car, and it has worn down at the point
where you usually stop and fill it.

I'd bet, if you run it a little lower, the rest of the range is OK. This
thing can be a real pain to replace; some of them are merely opening the
trunk and removing a cover, and some require dropping the tank...

Can you verify that the tank is actually full? It could be the filler
check valve or the fuel level gauge. The check valve might have gotten
flooded when you pumped a little more in that time. Not sure how long
it takes to clear.

Hi, to get to the sender, just pop the back seat up, you will see a
metal plate,pry up with screw driver watch the glue, or black tac, you
will see the wire plug, don't force it off it has a lock, you will see
it, same on the line, it should have a little yellow clip on the fuel
line easy on it, as breaking it wiill put you out of a ride untill Toy
can get you one, 8 mm socket, remove the bolts, making sure not to
damage the rubber gasket, remove sender and pump, being you should have
your new one from Toy, don't use aftermarket, wast of money, you should
see how to remove old one and replace new one. This job pays .6 at
Toy, with out daignostic time. You go to parts counter, buy part, go
to service desk, tell them you would like it installed, if you do it
yourself release tank pressure 1st. Clean gasket well, I like to use
silicon to make sure I get a clean seal or you could get a po440,
po441 and po446, depending on how big the leak is, evap codes, check
eng light. Oh, where you live they may charge more. This is easy if
you like working on Toy's.

All this effort and ezpense just because the needle on the fuel gauge stops
"just below the full line" ?
.....and this is a ten year old automobile, right?
sounds like putting on a full body cast because you've cut your chin
shaving.

True, if it's the sender unit in the tank it doesn't really matter.
Except if the tank-fill check valve flooded and caused early cut-offs
then one needs to be careful. It might flood the carbon canister. In
general, don't pump more fuel after auto shutoff.

So what if it DOES flood the carbon canister...as long as one lives in a
jurisdiction that doesn't mandate regular inspections.

This might be a long shot but when you fill up your tank, while the cap
is still open rock your car up and down as if you want to wake the
people sleeping inside the car, hopefully this will get the air out of
your tank if that is the problem. Do this the first time your pump
clicks and then refil.

If the canister fails vapor pressure tests only MIL will come on. It
won't cause the computer to go open loop I don't think. But if it
affects tank venting then you'll have pressure/vacuum related problems.
