the bx's are self priming . just turn key on for 10 secs and back of and on again several times. it will bleed out.if your having issues - i'd check the feul . just like mine earlier i had mine gelled up. i swear i added the white power service back in october and i see crystals in the tank. i added 911 and sure enough it ran nice again.
Yes, your engine is self priming. I would second on the Diesel 911... sounds like you have slush in the tank.
