Lifters and Oiling

So it looks like I have three options going forward:

Option 1: Replace just the lifter, and then check the oil pressure. Replace the pump if pressure is bad.
Might risk damaging the new lifter by breaking it in with a weak pump?

Option 2: Try to check the oil pressure (while running on a dead lifter) to determine the oil pump condition. If bad, replace pump when I replace the lifter.
Probably not great for the cam and rockers.

Option 3: Replace both the pump and lifter without checking the pressure.
Might be unecessarily time consuming and expensive.

What do you gentlemen think is the best way forward?
