whats up guys i have a 02 silverado it has the 4.8 engine and i installed the LS1 intake and im installing a fuel cell and a inline fuel pump my question is what do i need to do about a return do i need one or is it fine if i do not run a return because as you know the LS1 intake do not have a return line like the stock silverado intake i just wonder if it needed a return or does it really matter and does the fuel cell need some sort of breather? ...any help well be appreciated thanks guys!!
