Here's the lamest question of all time I suspect. But, for the life of me (I've spent the last hour trying) I can't get the high-pressure hose to thread into the power steering pump...it simply will not start. Is this always a PITA or is there something wrong, I have two pumps and two hoses they are both the same.
