Replacing entire fuel system. What components ?

I'm going to replace every component of my wagon's fuel system just to have a clean slate.
So far I've ordered new fuel pump + fuel filter + fuel pump relay + fuel pressure regulator + injectors.
I'll replace the hoses too.

Anything else I've missed that I should replace ? TIA.

You didnt' list the fuel pump sending unit, unless you bought it bundled with the pump.

If you truly want to replace the entire system, there are the hard lines from the tank along the frame to the engine compartment. Though not sure why you'd want to unless they are rusty.

I'm not replacing the hard lines. They're good. I just want to replace all the old 20 year stuff
that's subject to ageing. Better do it at my leisure than to do it on a cold winter night.
