Sorry that it took so long to fix this; the problem was simply that the item name and the recipe name were different (for some reason, the internal recipe name is "empty-jerry-canister", while the item name is "empty-fuel-canister", no idea why the discrepancy lol), so it wasn't being picked up by my standard reversing function.
I added it in as a manually defined reverse recipe, so it should be fixed as of v8.1.18
