Re-use your in tank pumps - a 3/4" copper pipe cap is a nice fit over the suction end. Solder an inlet pipe fitting to the cap (drilled) and JBWeld it to the pump - add an additional lengthwise hose clamp if you want. There's no pressure on the inlet other than a foot or so of fuel head pressure. Adapt the outlet fitting as needed, but this is high pressure, so its got to be good.
