Score one for Blue Chip
I've installed the Blue Chip pump in my truck and I must say it seems to run smoother than it ever did before with the OEM pump and the first Dodge rebuilt pump. Regarding the claims of better fuel economy, I'm seeing 22-23 mpg in my local driving lately, (last three tanks, hand calculated). With my old pumps, I saw 23 mpg only once and that was prior to ULSD fuel, so the claims of better fuel economy might be true, but perhaps not significant.
Blue Chip provided me with a loaner gear puller, and was very supportive with instructions which was important to this shade tree mechanic. This is now the third injector pump in only 85k miles and I certainly hope it's my last.
