Yes to all that.........and plus........if you have a working fuel gauge and know how many gallons the tank holds, refill when the gauge shows 1/2 full.

This way you'll know approx. how accurate it is.......if you have a 60 gal tank and it refills taking 30 gallons, well then your gauge is accurate.

Do it again when it shows 1/4 tank and see if it's still reading accurately.....and takes approx. 45 gallons to refill.
