Hey guys..... I am doing a 3.4L to LS1 swap and I had a question about adding an inline fuel pump.... Basically I was wondering if it was possible to run the motor with just an inline pump. The new tank and pump assembly i bought obviously doesn't work. I was just wondering what I would need to do since the system is returnless....... Do I need a pressure regualtor or how do I do this... HELP PLEASE!!
