Seen on youtube, "powerstrokehelp" dude, drilled out the fuel rail end plugs...not sure what they're called, but is there any benefits to it, and would you guys approve of this mod?

 

IMHO, you won't see any noticable benefit from doing this. Installing a Regulated Return system would give you better results when installing larger feed lines and getting rid of the restrictions in head fuel inlet fittings.

 

Cool, thanks Roland..(give the big thumb up, but just reached my 25 count). Had thought about the reg. return, but RiffRaff FRx just seemed reasonable.
