squatting dog said:been using these square 5 gal. jugs since the 80's.
BTW, you can sometimes find these 5 gallon racing gas jugs at...of all places, farm co-ops.
Just another source to check out, I dont know what the prices would be now or the type of spout they would have, but I just bought the threaded barb that screws in the top and attached a short hose to it.
Works great!
