You will actually run into a different problem than gas mileage when you feed a diesel vehicle from a fuel can. Only a portion of the fuel that is pumped actually gets burned....the remainder goes back to tank. It's purpose was for cooling and lubrication of the injector pump system. So as a result you will find that the jerry can will empty rather quickly, and eventually after a coupel of them, your fuel tank will be overfull.
I found this out during a typical bitterly cold Feb ex here in Shilo. One of the LSVW MRTs froze it's lines, and wouldn't run. It was impossible to thaw it, so we strapped a jerry can onto the front of the truck and fed the line to the fuel pump. The two guys running the truck had to continually siphon the extra fuel out of the main tank and put it back into the jerry can.
It wasn't perfect, but it got them through the ex.
In hindsight, I could have run a line from the return line at the tank back up to the jerry can. But the conditions were never there to use it again.
There are jerry can adapters made up for these and similar purposes. There were two types....gravity feed and siphon feed. When the new plastic cans came out, they also made similar adapters for use with the outside threads of the new can, although the earlier adapters could still be used sionce the cans had the early threads on the inside of the neck.
