92 Camry. How does a gas station pump determine when the tank isfull ?
Hi,
Recently my fuel gage stop working. It now point towards the 3/4 to full
mark.
I am wondering how does a gas station pump determine when the tank is full.
The reason I ask is that I thought I had 4 to 5 gallons in the tank when
the fuel gage broke.
When I went to the gas station to fill up, the attendant could only add
another 5 gallons.
I thought I needed about12 to 13 gallons more. My manual says I have
about 18 1/2 gallon capacity.
I could have been wrong and gage had broken earlier than I though and I
had a lot more gas in the tank.
I plan to use the trip odometer to help me determine when to fill up at
the gas station.
Based on a conservative 10 miles a gallon, I will fill up after each 100
miles.
Thanks in advance for any information.

full.
A cockroach with a small but powerful flashlight is sequestered inside a
hidden compartment at the end of the nozzle. When you start to pump, he
shines his light down the filler neck. When the tank is close to full, he
hits the Push to Talk button on his miniature cell phone and tells the
foreigner working the Quickie Mart cash register to stop the gas flow.
Next question please....

Best to go ahead and get it properly repaired. Check the sending unit
in the fuel tank, under the rear seat cushion.
Had a similar experience, and the "odometer method" worked well for a
number of months, until one day, in the "fast lane" having just left a
freeway interchange with fast moving, heavy traffic, the engine
sputtered and stopped running.
Perhaps that answers your first question. Sometimes the auto cut off
on the filling station pumps are inaccurate and vary enough to cause a
real problem at some point.
(I was able to move quickly across four lanes of traffic and coast all
the way down the off ramp to a mechanic, but easily could have not
been so fortunate).
It's been a long time ago now, so I don't remember all the specifics.
I think I tried to leave a minimum 100 to 150 mile reserve in my tank,
and I know my calculations were correct, IIRC there should have been
something like 250 miles left in the tank when the engine ran out of
gas in my case, so you really cannot trust the pump shut off -- and my
gauge read accurately (so I thought) when full -- so that should have
been a verification the tank filled.
Anyway, just plan to have the gauge repaired when you can.

Thanks for that intelligent and helpful reply.

I was hoping not to have to spend $150 - to $200 to get this repaired.
Thanks for the suggestion, Daniel.

JoeD <com> spake unto the masses in
news:01KQb.23364$news.atl.earthlink.net:
There is a small square-section rod in the filler nozzle. When the gas
starts splashing back, it pushes this rod rearwards, tripping the mechanism
and shutting off the flow.
It's only as accurate as the amount of backsplash your tank (or its filler
neck) tends to give. some cars are so designed that you need to insert the
nozzle only part way in to prevent early shutoff.

Another posting today reminded me that the Camry has a red light at
the bottom of the fuel gauge that reminds you to fill up before
running totally dry. My older Toyota truck that ran out of gas didn't
have that.
Still, the manual recommends not letting the level go below the 1/4
mark to help keep enough gas in the tank to cool the electric fuel
pump, so you could attempt to do that with your odometer calculations
with the red light as a backup.
Just think, if you had a new car, you'd probably be paying $150 - 200
or more every month.
If you can use your own tools, or know someone who can, or check
prices at an independent mechanic, you may be able to find a better
price.
The Haynes repair manual shows how to do this repair. You remove the
side bolsters on the rear seat, (one or two bolts) then the seat
cushion (lifts out from the bottom). There is an access plate in the
top of the gas tank that will then be visible, and you remove the four
or so bolts to lift out the access plate with the fuel pump and gauge
sending unit attached. (Haynes manual, under $20, has a photograph of
the plate lifting out with the sending unit and pump attached, so
perhaps you can determine whether you want to try this by first
looking at the repair manual).
If there's a Toyota dealer nearby, you might want to check the price
of the sending unit. Don't know others experience, but have found
often the price can be reduced just by asking respectfully, whether
they can sell to you at a better price.
