Yep known for years !!!!! then when you try to publicly share this info and solutions people either don't listen or turn threads into pissing matches plus these so call engineering firms have big ears let them figure it out themselfs they don't share there data with us lol. I have flow data with almost all the aftermarket pumps and some OEM pumps compairing them to each other and have been running a solid no issues solution for over year now. Next up for me is fueling solution running on E-85 its slow moving Arnold takes too many crazy projects in his shop. Lol. Bob. G
