Alright guys I just bought the upper half of my fuel system. I have the Aeromotive rails and regulator, fore Y block, #8 feed lines, and #6 return also #4 for fuel pressure gauge and am running glenns performance sumped tank . I am looking for the -10 and -8 feed line and -6 return as well. Where is the best sites to buy these from? I can't seem to find the -10 on most sites, but I'm sure I'm overlooking it all? Any help would be great. Also what length will I need for the rest of the set up???
