Anybody know what this is?

Some sort of fuel saving device maybe. Im guessing you would fill the red tank with something and likely a pump inside it which would be activated off the relay mounted to the side of the fuse box. That would fill the white container then drawn into the engine using vacuum from the intake. Best guess I could come up with...

Its weird. The red box indeed has terminals and leads to the fuse box. The hose leads to the white top cup which has another hose that leads to nothing. guessing it used to be plugged into something. the red box looks like a gas can haha.

Maybe an early version of the Flux Capacitor.

I don`t know where you are located but was there a snowplow mounted on your H2 at some point?
