Some rebuild companies swear to just use these little plastic plugs in the two ports and mount the whole thing in a vice. Then just pump the piston until no more bubbles surface. I use two homemade lines from standard brake line in each port and curved them as drastically as they would go BUT still was able to pass air through them from the ports up and flipped back into the top of the bowl. They need to reach far enough into the bowl that the end will sit under the surface of the fluid in the bowl. Mount in the truck if you have a buddy or in a vice if you are by yourself and pump the piston slowly. Never move the piston more then half way down it's bore or you risk tearing the primary or slave wiper seal. Continue to fill the bowl as the air is bled out of the lines. Install the MC and hook up the lines. bleed the brakes starting from the farthest wheel from the MC (right rear). Again, don't allow the piston to move more then half way or you ruin the wiper seals.
