1. IMO none, get injectors to suit the application

2. Usually never, if correct injectors are purchased

3. Depending, yes or no.

How hard is it to hook up the standard reg onto an after market rail? Is there a universal kit or something.

Adjustable FPR you can squeeze an extra ammount out of injectors, but you move away from a fine mist (factory pressure), to a leaking tap type of spray pattern.

As ^^ said never, but why do you need one is it to push more fuel out of the injectors or is it to fit a aftermarket rail?

If its to fit a rail put bigger injectors in at the same time other wise you dont need the rail.

I think a very small rise in pressure to keep injectors below 100% duty is ok but you will sacrafice spray quality.

Bigger injectors are ALWAYS better.

Adjustable FPR you can squeeze an extra ammount out of injectors, but you move away from a fine mist (factory pressure), to a leaking tap type of spray pattern.

This would occur with low fuel pressure (ie stock fpr and pump, bigger injectors) rather than higher fuel pressure (adjustable fpr) would it?
