Just a quick fuel question, for a swap into an older vehicle. I am getting ready to help a friend do a TBI swap into a '74 Blazer, but it does not have a return line. What is the best way to do one? Should I use rubber line going back to the tank, (and does the return need to be FI rated?), or does it need to be hard line. I am planning on using an inline fuel pump and using the original feed line. Also, where are you guys putting the fuel filter when doing an inline pump?
