Anyone know if you can lower the fuel pressure by putting a resistor into the power line going to the fuel pump?

Why would you want to do that? IMHO that would be just asking for a possible lean condition on the "big end" and possibly some burned pistons. An adjustable regulator is a much safer alternative.

NO.

why do you need to lower it?

the correct way to lower it is by adjusting the 'fuel pressure regulator' :)

Lowering fp would be to accomodate different injectors (sort of a rough initial tuning). As for a regulator, doesn't that require either (a) getting into the fuel tank, or (b) having a new return line back to the tank? If there's a way to have a regulator in the engine compartment without added new lines please let me know!
