Question oil pressure

when cold my oil psi is around 30 at idle but once warm it drops to practically zero, at around 2000 rpms it reads about 20. what can i do to atleast make this a little better, will a new oil pump do the trick?

First make sure the reading is accurate, the sender or even the gauge could be going bad, or possibly the constant voltage unit. If it is as you describe after testing with a mechanical gauge you've probably got loose mains, and only one remedy for that. A new high volume pump may help, but if you have the pan of why not go the extra step?

most gauges are not accurate below 10 PSI some aren`t below 13 PSI. We`ve ran a slightly hopped up 350 for years now, and at hot idle, the gauge goes to zero, so if i didn`t hear anything rattling i wouldn`t worry about it. also the rule is 10 psi per 1000 rpm, i`d say as long as you have that, your ok.
