The pump is tapped for 1/2 pipe. I do not want to neck it down. I'm using a 392 pan which is a common "center" sump but more toward the front. I do have a std vol pump/matching pickup (for that pan) but I want (need) the hi vol pump tapped for 1/2 along with the other oiling mods. I will see what Steffs has. Thank you!
