Probably just run out of fuel or something at the carburetor. Or nothing at all could happen.

...if you've tried blowing in it...it only goes one way...so you do the math about what would happn if you put it in backwards...pretty much what ^he^ said

Yup... arrow points towards pump, and if you put it in backwards, fuel doesn't get to the pump.

Worst case scenario, if you really kept trying to start it or kept the pump running dry, it would burn the pump out. Most likely it just wouldnt flow fuel, you'd realize what you'd done and switch it around. Sounds like you got it right.

Yeah, the order is Tank, Filter, Pump.

The filter protects the pump from getting junk into it and killing it.

I have not done it yet but that is what my books says....
...and it makes sence.
