I have a 2003 Trailblazer ext that im replacing the fuel tank because the filler neck cracked. So I've had a hard time finding the right tank to fit but after weeks looking I found one. The only thing wrong is that the tank is from a 05 model which in 05 they changed it to a no-return fuel system. So I need to know if there is any way I can make this work in my 03.
