On the aftermarket fuel rails....does it matter which rail/fuel line goes........like on my 4.8....it has two fuel lines on the left hand fuel rail.....if you put aftermarket rails on.....which line goes to which side?

 

Well I Have The Aeromotive Fuel Rails And Reg And Pump If U Use The Truck Intake U Will Havr To Make The Lock Down Brackets.i Am Changeing My Whole Fuel System.the Fuel System I Think Is The Most Expensive Part 180. For Rails,130 For Reg,and 78. For Half The Fittings,289 For Pump,100 For Filter.

 

FAST makes rails too along with Nasty Performance. But if you do that you will have to fab up your feed and return lines to adapt to the rails. Truck intake is different too. Its set up for shorter injectors than the LS1.

 

AND U HAVE TO MAKE THE HOLDERS FOR THE RAILS.JUST DID MINE TONIGHT.
