I'm troubleshooting a 1994 John Deere 690 ELC that keeps getting air in the fuel system. I've already replaced the water separator, lift pump, fuel lines, and glass fuel filter. The machine runs fine for about 20 minutes, then loses power, stalls, and won't restart until I reprime the fuel system. I also noticed air bubbles in the glass fuel filter.
