a regulator after the rails is better, the one in the tank depends on the amount of hp you are running.

if you decide to go boost then you need to upgrade.

as long as your in your ~58psi fuel pressure range..

My stock reg took a ****, I ended up putting one post rails as mentioned, works like champ. But, to regulate it, I had to bump up to a -6 return line, the stock return was too small and a bottle neck.
