Window down, black rubber boot removed 2-10mm nuts have to come off. I think I used a 1/4" drive ratchet/socket and a ratcheting box wrench. Also I believe inner door panel also has to come off as you need to unplug some of the connectors located inside the door.
But that is from memory as I last did it years ago...
I had the guys that installed my fuel pump use the short piece of the hose on mine. I think it makes a tighter connection if clamps are installed properly. The pulsator was used to quiet the pump. Noise was not a problem with the hose. either one will work.
