Unhappy Gas Gauge

I just got a 1988 Ford F250 with Dual Tanks. I filled both tanks to full capacity. I put the switch on the front tank and drove the truck for 180 mile and the gauge needle is still buried full. Does the gause read the tanks together as one? I have switched from front to rear tanks and they both read full. Or does the gauge only read one tank period, probably if this is so, the rear.
I had a 1990 f150 with one tank and the gauge was almost acureate.

These trucks are famous for gas guage problems. My front tank guage quit working 6 or 7 years ago on my '92. The rear tank still works but is not very accurate. It will fall to about a quarter of a tank or so and stick. This problem should shame Ford.

I also have a dual tank problem on my 87, the front tank gauge does not work..and the rear gauge isnt very accurate. I'm thinking about replacing the sending unit in the front tank, I think that is what is wrong.

Since the gauge is the same for the two tanks, displaying only which tank you are on, thats a logical conclusion Peach. I did my rear tank not too long ago, and now the gauge is more accurate (as compared to dead). Now, apparently, its time to do the front tank. I've been putting it off for a month just because I don't like lying under the truck when its blistering hot and humid out, but its time to do it. At least its empty this time!

The sensor mechanism was less than $40 at my local Ford dealer. I couldn't find a unit at any of the usual aftermarket places, and coincidentally they had it in stock - even nicer. I don't remember the exact price because I walked out with a ton of Ford-only parts at the time, but it was less than $40. Maybe $35ish or thereabouts.

The fuel pump is the expensive part...

You can buy the sensor, and the pump seperately, or you can buy them together as one unit. If the pump works, I'd leave it. When I did the rear tank over, I chose to just replace the sensor, and a month later the pump died, so I had to take the tank out again.

Thats why in the front, I'm just replacing both so I don't have to deal with this nonesense again.

You can also set the float level on the sending unit, to make the gauge more accurate. Just figure out which way it need to be tweaked and bend the rod that the float is attatched to a little bit.
