I know our 92-96 fuel gauges are notorious for being inaccurate, is there anyway of custom fitting an autometer fuel gauge to read both tanks? I like my gauges to be accurate? Please someone shed some light on this issue, because I am getting tired of using the trip odometer for fuel capacity estimates ;-(

 

I didn't know the fuel guages were noted for being inaccurate? What is normally the problem with them? The only thing I have noticed is the sending units in the tank are notorious for going bad. But replacing them usually fixes the problem.

 

Well I am trying to figure out a way to get the gauges to read accurately... I have to use the trip odometer unless I want to be stranded in the middle of nowhere which no one likes by the way. I just thought there might be a cheaper solution other than buying the whole sending unit for a 92-96 F-150, that cost some bucks to replace doesn't it?

 

Does it read 1/2 a tank but runs out of gas?

 

Not exactly, but when the needle is low close to the E, it will run out quick which is obvious, but it really varies when using 4x4 or 2x4...

 

The reading will not be linear across the scale because the tank has a shape to it. The sending unit reads linear, but the tank is smaller or larger at different fuel heights, so the guage will fall slower or quicker.

One key to knowing you are near empty is the gauge needle reacting a lot( the low fuel in the tank is hitting the sending unit more violently) and then it doesn't react at all(the sending unit has hit the lower stop, and you have approx 3 gallons left).

Those year trucks are all fuel injected or have fuel pumps in the tank. It is not a good idea to keep running a fuel system low with a electric pump inside the tank. The fuel keeps the electric pump cool. Running it extremely low frequently can shorten the life of the pump.
