Fuel pump assembly design coming along

Have been designing my future fuel pump and filter assembly. Will be changing the whole fuel system to 1/2 stainless pipe for supply and 3/8 stainless pipe for supply to the cylinder heads and fuel return. Project will be done in four phases:

1. Fuel pump and filter assembly

2. regulated return and fuel bowl delete on engine

3. fuel pick-up in tank

4. lines between tank and pump assembly; pump assembly and engine; return line.
