Been thinking about going with and 5.3 and been thinking about all the costs that I will need to do the swap. I have an 83 with dual tanks. Can I use everything I currently have and just hook an external pump to them? They won't have baffles like FI tanks have is that ok? Also all of the rubber lines that are currently there will need to be replaced? Can the stock tank selector valve handle the pressure or is it just "presurized" after the pump?

Thanks in advnaced! I'm a newb!
