Fuel pressure is set by the pressure regulator and pumps have a wide range, a 100 PSI pump against a 30 PSI reg will only make 30 PSI. However some pumps have an internal blow off valve / have limited power so a 30 PSI pump won't always work at 100.

Yeah, I get that the pressure regulator determines the pressure, but I didn't know if one pump would generate a significantly higher output than the other and become an issue that way...

That's a good point, but in this case I'd only be running three injectors at a tie, so that's OK.
