I ran my F7 out of gas trying to burp it on its side. I heard the fuel pump whine, and it leaned out and stalled. What color is the wire that needs to be unplugged to prime the pump? I pulled the rear smart valve out and its collapsed. How do you free it up? There must have been air in the system after I raised the rear end up to stud it. I couldn't get any heat in the running boards after riding it for 5 minutes. Make sure the new procedure is followed, because I had bled mine previously with no air coming out. I must have freed up a pocket of air whenI raised the rear.
