Can someone please advise; have narrowed down no fluid squirting, down to the 't-connector'. Stealer wants $12 for this white plastic part. At Pep Boys, they have similar item, the caveat is, the t-connector Pep Boys has is a different size. Does this matter? The object Looks Exactly the Same, does the Same function, however, the CIRCUMFRENCE of my existing (lame) one is larger than theirs. I could see how the ENDS have to be the same size so the tiny clamp and hose fit on, but what about the rest? The length is the same also, just the circumfrence. Please HELP. Can't see thru windshield.
