If your going to replace the pump i would go with a TC pump for PSC motorsports. There a little pricey but well worth the extra cash for 300 psi and 4 gpm flow rate more then the stock pump. Just my two cents.
Trail Gear also sells a tc pump now with all the brackets and pulleys and belts you need for a good price but its Trail Gear and well.............................................I am not a big fan of theirs
Good luck
