fuel rails
I think I posted this in the wrong thread before but I am lookin at upgrading my fuel system I have already done the cop's and injectors to a 4 hole 19lb so I was wondering if I could install a set of gt 500 fuel rails on my 2000 f150 5.4 sohc would it be to much fuel or would I get any gains from the swop thanks to all who answers
