To Reproduce
download the mods, (jei too if you want)
either place down one of the engines and pump diesel into it or just check the uses for diesel fluid itself

Expected behavior
engines accept diesel (and other fuels)

Screenshots

and a screenshot to show that the diesel is in the engine and isnt just not getting pumped in

lmao im such a silly goose

I haven't even touched diesel generators or diesel. Do you have any other mods installed? Also make sure that you are pumping fuel into the diesel generator correctly. Also have you tested without cac?

the second screenshot shows that you can pump diesel out of the engine so there is diesel, and if you replace the diesel with ethanol then it works
after removing ONLY cac (keeping almost unified create and cdg) it suddenly starts working again so yes, its an issue with cac all the mods i have are at the top

I have replicated this and it's indeed fixed by removing CAC.

Note that Diesel Generator's fuel tooltips disappear from fuel buckets that won't work while CAC is installed, so maybe this has something to do with how CAC handles fuel tags?
