I just found this odd and wanted some input and maybe is if there is an issue.
So I've had a 12mm stroker pump for a few years with my stock injector on my LBZ. It didn't take more then 50% throttle on any tune and the stroker would pull more fuel then my dual Kennedy pumps could provide according to my fuel pressure gauge. I just though the pumps where weak or it was just to much CP3 for them. Now with my S&S100over's the lift pump holds great. Better then it did with the stock cp3 even back when I put them on and I had 36K miles. So I'm a little curious why this is? My stock injectors weren't great, but far from bad. Old stockers just returning to much fuel and the 12mm was running at full tilt or are the S&S's some how different leading to this?
My only concern that I might have an issue is that my factory return line ain't in the best shape and starting to kink. What are some of the systom's of a blocked return line or how would you diagnose it other then a pressure gauge?
