When you install a larger fuel tank, transfer flow or super tank can you recalibrate the cluster to display the range of the tank correctly

Thanks to all

I have the 62 gallon supertank. I usually put in 55 gallons. My guage stops at full (40 gallons) and keeps filling to 55.

When I see the guage fall off full I know I have used 15 gallons. 3/4ths is around 30, 1/2 is 20, 1/4 is 10 and empty is 5 (reserve to me).

You get used to it. Watch it when you fill up and you will know what you have. Or just watch your mileage as you drive and empty the tank.

Didn't I read somewhere that TechII can change the size of tank?

I was under the impression that the fuel gauge would show right but the range to empty would be off

If I understood the question, it's the sending unit in the tank that needs to be matched to your truck. In '04 GM switched to a 5 ohm guage.:eek:

If I put a larger tank in I would like the range to show properly in the display
