Thanks for the heads up. I plan to upgrade the fuel feed system as well. I just need to figure out a few minor things as well as what size line to run (guessing 6AN hose???). I would rather replace the fuel feed line at this time since I doubt the stock line is rated to support a high pressure fuel system.

In doing the above with an external filter, should the stock filter be removed or left in place (to provide somp protection to the fuel pump itself from picking up debris?
