With the mods Dave has planned, he's going to need to upgrade the fuel
system at some point..............
The Holley 255LPH in-tank pump, hi- flow fuel rails, and the Lincoln
Navigator
injectors will more than likely be needed eventually.......
My '01 needed to be upgraded, as it started running out of fuel on a dyno
test
last year........the injector swap took care of the issue.
I 've added nitrous and have turned up the boost a little more so a fuel
pump swap and regulator install will be next.
