I am installing a supercharger on my dad's 03 marauder, and wondered what fuel pump to install for 400+ rwhp. Can I use a stock 03 cobra pump, or maybe an SVT focus pump? Which fits the best, taking cost into consideration? I have a couple 03 cobra pumps sitting around. I have already bought a BAP to run also, but his original fuel pump has 90k miles, so it is probably time to change it. Thanks.
