The attached is the trunk just prior to NOS tank installation (It's a one gallon aluminum fuel cell. I'll take a pic tonight of where and how I mounted everything. In a nut shell, I built a retangular frame that allows me to mount two big FRAM fuel filters and one Holley elec. pump. The NOS pump is mounted high up on the side just behind the gas tank but way to the passenger side. All located between the tank and the differential. If you look under the car from the rear you can just see the lower tips of the filters but nothing else.
I run 1 independent lines one from each pump, both pumps have their own filter. The carb fuel supply comes directly from the tank pickup and is the only non-AN fitting in the entire system. The NOS fuel comes from a separate tank (foamed for anti-foam/splash) mounted just forward and to the side of the battery box in the trunk. All hard lines are 3/8 stainless, all connectors are -6 A/N and all flex lines are steel braided -6.
