Yesterday Jim O posted a video on Facebook where he mentioned changes made to Del's fuel system that had contributed greatly to their recent performance gains. During testing at Indy they made the same changes to their other cars with good results. He said Dell and Don Jackson had come up with a valve that eliminated three other components and saved 9-10 pounds. The new "All Valve" makes for a much more simplified fuel system. The new system "gets fuel in the way we want it" and is easier to tune and obviously runs like stink. Does anyone know any facts about this new system?
