It will be the entire fuel system between the sending unit, engine bay, and back again! Our new version of VHR rails that we call our FPD rails (fuel pulsation dampened), external regulator, stainless hard pipe, and teflon with SS braid hoses.
The stage 2 kit with just the stock sending unit will be good for 600-750rwhp depending on fuel pump used and type of fuel/dyno. With our twin pump assembly, or with the RRP with added pump, the sky is the limit!
