Yes you need a pump. Walboro has a 255 that requires no mods to the fuel pump basket.

A 50 shot is a waste of time. The 75 will be noticeable, but you'll be grabbing the 100 and 150hp jets by the second bottle refill.

Go ahead and put the pump in with the nitrous install, better safe than sorry.

I don't know much about the in-line pumps. I would go w/ a 255lph in-tank. Walboro now has one that is very easy to install. I got mine from Full Throttle Performance.
