oil pump help

Ron Gusack · 03-05-2016, 05:45 PM

My current pump uses the cap as the pickup and returns the bypass oil to the pan, which has always seemed like a good thing to me. That Melling doesn't look like it has the grooves in the cap and wall of the body. Is anti cavitation over rated? Somewhere around here I have detailed info on how to drill the cap to get the bypass oil straight back to the pan, but I haven't been able to find it. Is it not necessary?
