I've replaced my fuel tank and everything up to the end of the filter. It is bone dry so I'm going to add some gas in there now. But I figured that there is going to be some air in the line. Can I just prime it a few times using my key to turn the pump on? Or do I have to bleed it at the rail? Any advice would help out, thanks!

So i asked on CT (cherokee talk) about a lifter tick i have. They suggested Marvel Mystery Oil. Got a bottle. They say i can add to oil. Directions on bottle say "next oil change replace 1qt of oil with MMO." Do have to wait for next oil change, or can i just put it in??? P.S. trying to convince my i can just add it.

Add: point being I can't seem to easily disconnect the wire connector at the back of the rail.
