If u haven't put fuel in the new tank, pull it and weld some fittings or a sump in it . I used 2 drilled out 1/2" octagonal pipe caps, and welded them to the back ,lower corners of the tank on both sides. Then just took a big pointed center punch and drove it thru them till it stopped , creating a large centered hole in the tank/fittings , w/ no drilling trash created. U then can put ur pump fairly close, behind and on the frame , where it will be close to gravity feeding. A big plus is being able to run 2, 1/2" canister type filters that will filter ur fuel before it goes into the pump. Mine has plenty of flow and keeps the pump clean. U can run shut off valves first to aid in filter changing and fuel line work. I then went from the filters to a y fitting , then into the pump. The external pump makes a little noise, "till I start the car!"
