Oil pressure is 0 at idle, fine above 1,000 rpm???

I have a 1990 Ford Bronco with 351 V8. The oil pressure drops to zero (red) after the engine is hot at 1,000 rpm or below, but is fine once you accelerate above 1,000 rmp. Has anyone had this problem and know what is wrong? How hard is it to replace the oil pump if this is the problem?

Thank you!
