What is everyone using to run new supply and return lines for a EFI system. I bought the MSD Atomic EFI and A Tanks inc tank and wondering what is the best option? Trying to get everything together to knock this out during my 10 day vacation in Sept. Unbelievable that the tanks inc paper work came with no list of included parts, took me reading through the direction to realize I was missing the pickup sock for the pump. The MSD instructions say it includes fittings for the included fuel line but there was no fuel line included. I was looking at push lock type hoses. The Tank has a 1/4 NPT on the pump for supply and return and the MSD has -6AN fitting. Figuring 3/8 supply line but haven't read what size return is required. These are some pretty crappy directions for a bolt on system. Also do you have to run a regulator on a return system...something else I have to buy?
