Float mount setup? It's more reliable if you don't use complicated setups

If you use a lift pump, you can use inexpensive, low-pressure fuel lines for the majority, only using the high-pressure lines & fittings in the engine bay. You can also use a low-pressure (cheap) swirl tank

Here a lot of guys put the EFI pump in the rear and pump fuel all the way forward. In the rear so they can mount the pump below the tank level. But you can also put the EFI pump in the engine compartment and pull fuel forward though low-pressure lines & fittings

In short, there are MANY ways to "do it right". The new systems don't even use a return line
