The eaby pickup tube measured. View attachment 1715273231Looks too thin to drill to 1/2". So if you do the standard oiling mods and drill passages to 1/2" the bottleneck will still be where this tube screws into the pump. About 22% less flow.

Agree. Still bigger than the stock pickup tho. That insert is really hard metal to drill. The reading on mine was .444 if I remember correctly on the milodon pickup.
