Hey, I've finally had it with the stumbling and what not. But can't really afford to purchase out-right from the dealer. But "poundage" injectors are the stock rating. Looking on-line and keep getting conflicting information.

 

The stock injectors for a 4.9 are rated for 14 lbs. @ 39 PSI. In actual operation, they flow more like 17 lbs. because they operate at a higher pressure (55-58 PSI)

They are easilt recognized by their grey tops. The more common 19# injectors (302, etc.) usually have orange tops
