Accuracy, Jerry Can vs Fuel pump

[Scooby074]

The feds set the standard (weights and measures). There should be a calibration sticker on the pump.

99.9% the pump is right and there is something wonky with the can.

When i mix fuel, i use the calibrated pump at the station to pump whatever volume i want, i dont trust the marks on the cans. The fill marks were never intended to be THAT accurate.

At work we had these graduated fill containers (think water picture, but with a spout and graduations) that you could use to check the calibration of your cans. Ive seen similar ones at NAPA i believe.

Well, I finally emptied my Jerry can and was ready to fillr' up again. I went to a different station this time and once again filled the tank to the 25 liter mark. I was able to put 28.5 litters into it this time, so I guess those tanks do expand that much. At least now I know the first station wasn't up to no good.
