I can do this where I spliced the new wiring harness in that came with the pump.

Yes. The only issue is that your meter is probably fused for 10 amps, and if the pump draws more than that you'll pop the meter fuse.
My meter will handle 20 amps for very short-term loads. It's rated at 10 amps. The fuses are hatefully expensive. No promises on your meter.
I would start and run the vehicle with the meter connected. Use the memory function of your meter if it has one, so you can review the minimum, and especially the maximum and average reading over time.

IF (big IF) the fuel pump relay is tight on all it's terminals, you could bounce that car like a monster truck and not have a problem.
