I'm unsure which fuel system parts are unique to LH 3.1 system.

Definitely:
AMM
ECU

Maybe?
fuel pressure regulator
idle motor
cold-start injector/valve
oxygen sensor

Also: LH injectors are spendy! Not sure I have a bad one... lumpy, shaky idle but strong no-stumble acceleration, except 1st/2nd shift of the day cold. Replaced cap/rotor/plugs (NGK)/wires (IPD), checked hose from AMM to TB, AMM replaced last winter thx to that frelling intake pre-heat contraption, TB cleaned.
