The 720s Are The Ones That Go On The Block Itself. The Ones That Are Hard To Get To. Then The Other Ones Go On The Manifold. If The Injectors You Are Using Are From A Gslse, Then They Are Orange In Color And The Factory Turbo Ii Are Red??????

Anyone Correct Me If I Am Wrong. I Dont Have A Turbo Ii Anymore And I Forgot The Colors.
