One of the guys at the shop just told me they want to use aluminum rather than steel fuel lines because it "bends easier" - but off a quick Google search I see several posts saying not to do this. Can anyone here provide me with more input? I may need to call the shop and put the kibosh on this idea. I asked if there was any advantage/ disadvantage and was told there isn't, but I question everything. I'm using an MSD Atomic EFI with a return line. Thanks for any input.
