I just did it for the first time last night, couldn't have been easier. Just use the tube RoverChic shows ya. All I did was put a funnel on the tube pour real slow with one hand and rev the engine with the other. Course my vacuum line ripped, so I had to rig up a new one, but even that was simple. And the smoke! Holy crap there was a ton of it, I mean, I knew there was going to be a lot, but damn. I did it last night around 9:30, and smoked out the whole neighborhood, course I didn't realize till it was smoking like all hell that there was no wind at all, which is rare in Oklahoma. Anyway, it's easy.
