So I've had Flan's mod 1.2.5 for three days now and I've just started playing legit without spawning items but I don't know how to craft most of the items, for example, the fuel can for fueling the planes and cars.
Could someone get a link to a recipes page or a list of the common recipes that Jamioflan doesn't have on his thread please.
Look at the OP, recipes for fuel cans are in the Simple Parts pack, recipes for the planes & vehicles are in their esident packs, as are the gun boxes. (All of the recipes are there, just under spoilers. You appear to have made a common newer-user mistake of not opening & reading spoilers in OPs, then making a thread asking why you don't know how to do stuff...)
Guns are pulled from gun boxes after choosing one if you have the correct amounts of resources in your inventory.
