I think this belongs here since it's an svt part. I'm looking at an 03-04 cobra tank to put in my 02 gt since I have the stock system maxed. New is a bit pricey for me right now so I found a used one. All I have is a picture which doesn't let me know if the pumps work. I was wondering if there's a way to test the pumps without being in the car? Or how much the dual pumps would cost to repair if they don't work. Buy now price is 550 + 90 for shipping. Thoughts?
