I bought a inline fuel pump from TPIS.com, it said the pump can support around 450 horsepower, my question is is this pump to much for a stock tpi system or will the pressure regulator take care of things, or would I be better off just getting a smaller pump for inline application. this car will never see more than 250 horsepower.

 

It is a bit overkill but the regulator should be able to handle it. I would keep it if it were me.
