Re: How many Sy and 92 Ty owners need lumbar pumps?
I don't know where the air would leak out on a completely stock system. I just know the air was leaking out of the bulbs I purchased because they were intended to be used on a blood pressure monitor, which is supposed to have the air leak out at a controlled rate. If you have all of the stock components and you're losing air, I'm afraid I don't have any suggestions. One advantage is that there aren't all that many components. Pump, hose, and bladder. If you cared enough to find out what it is, I would take off the seat covers, remove the stuff, and immerse them in water to see where the leak is. I think that's something very few people would do because it's such a pain in the ass for something so minor.
Just my :2cents:
