The MF's that came up with those new [bleep] spouts never used them much I'll bet. They need to stand there and fuel up a skid steer and have fuel running all over them, bastids.
Now days a good funnel rules.
No they didn't/don't. They don't care anyway because the design is supposed to comply with some [bleep]-up environmental law. I usually wreck the innards of the spout and drill a vent hole up top that I can close off with a coarse-threaded bolt.
[bleep] the eco-nazis.
