Priming an Inline Filter on a Motorcycle Carb. I gotta get home!

I use inline filters on my motorcycles all the time. BUT, sometimes the fuel will not pass the filter and go to the carb. I set up a lab to find out the best way to 'prime' a fuel line with an inline filter. Let's face it, if you're on the road and need to change the filter mid-ride, you still need to get home.
