Pull tank or buy new guage?
 

I purchased an after market fuel gauge and it works except the damn sender
needs calibrated badly. I've never dropped a tank or calibrated a sending
unit before so I'm not sure if it's worth it or should I buy a "real" OEM
gauge for $$$ and just be done with it? Just weighing my options.
Thoughts???

Re: Pull tank or buy new guage?
 

I simply make a mental note of the mileage when I buy gas, and in 200 miles
I pull into the station and get some more. Gas guages are highly over rated
as a device that supplies any sort of useful information.

I am not aware of any calibration procedure for a sending unit, I always
thought they either worked or they didn't. I suppose they could be prone to
getting dirty and then not work correctly - but you clean them to fix this
problem, you do not calibrate them.

If you decide to drop the tank, you should do it when the tank is empty. The
bolts are going to be a pain in the ass, and you will get dirt in your eyes.
The hoses that are connected to the tank should all be replaced. I think you
should be prepared to replace the sending unit because I really don't think
there is a way to calibrate it. You may be able to clean it with contact
cleaner or equivelent, maybe fuel injector cleaner, but I can't imagine any
adjustment beyond bending the arm that the float is mounted to. (I took a
sending unit out once on my Dad's pick up truck, and the float was rotted to
the point that it would fill with gas and sink, then when the tank was
really empty, the float would drain so that a full tank would be indicated
immediately after visiting the gas pump, and for a day or two afterwards.)

Hmmm.

The stock fuel gauge has a voltage regulator on it for it and the Temp
gauge. If you feed 12 volts to the temp gauge you will have a dead one
fast. It takes 5 volts.

Here are some good schematics on the system. Maybe you can play around
with a resistor in the line rather than dropping the tank and bending
things.

Re: Pull tank or buy new guage?
 

It's very easy to calibrate the sending unit. Mine was reading to much gas.
Drop the tank, pull out the unit. See that metal arm that has the float on
it? Bend it. Up for reading to high, down for reading to low. I just
guessed on mine and endid up pretty accurate.
