You can use the stock rails, id get a 255 pump in case you plan on using a supercharger or nitrous later, as long as you got an adjustable regulator you can tune it down where needed.

stock rails will be fine

no there is no turbo or supercharger in the future, after these mods im done as far as motor performance. so around how much HP should i have when i finish with these mods along with the mods i have now

ill also have to have a custom tune

who says you'll need a custom tune?

URLACHER54

most of the people on here have said it would need it with those mods

It would help but since you have a fox and your keeping it prty simple you dont need one also just use a 190 pump then.

so with out the tune it wont run too lean or rich, i just want it to run as well as possible with the mods, so i can light up my cousins Grand National (stock)

You still won't have a chance.
