what size/kind of oil pump is right for me? which kind?

this is what i'm already running:
2332
drysumped
cummings pump
plumbed with 3/4
sees 8000rpm

i think i damaged my oil pump (stock size?) when taking it out last time. i have a leak in between the pump and block ONLY when i turn it off. it pisses out a little then stops, with no pressure just pours like its draining. so im looking for a replacement ? im probably going to silicone it tonight for the time being.
your thoughts?

thanks,
pete
