If you have plans down the road I would go with the 255intank pump or stay with the 155 and when you upgrade your engine just get an inline pump to boost pressure just to be safe fuel wise. Which ever pump you choose just make sure and change the filter and you should be good, as far as a regulator I have the $15 one that screws into the fuel line under the hood and im running at about 35psi but I would of got the one that sticks out from the cowl area if I could do it all over again so I can see the pressure from my drivers seat.
