How to Prime S60 12.7

You're showing your age. Hahahaha

 

No injector lines on that engine. Unit injectors with a fuel supply passage running through the cylinder head.

 

Shop air in the fuel tank works like a charm. A rag and a blow gun, all you need. Doesn’t take much pressure to push the fuel. That’s the cheapest easiest fastest way. No theory or debate needed. It works. Newer engines have a priming port, even newer ones have a priming pump.

 

Let me know what the problem was. Mines been drawing off one side only. Probably my shut off/ return valve. They’re expensive and since discontinued because of problems.

 

Blocked vent easy. Should be able to blow through vent hose on each tank. If not, blocked.
