1993 legacy 2.2 AWD. Is there a way to tell which fuel pump is the right one without ripping the pump out of the tank? Was looking to order one online but I started noticing they were different sizes (1 1/2 inch, 2 inch, threaded type, plug type.) Conveniently they were all listed as "direct fit" and "fits 1993 legacy 2.2" Really dont want to gut the car and let it sit for 3-4 days till the mail arrives. Is there anyway to tell what pump to order beforehand or am I stuck yanking the pump?
