Review on ACDelco 18M737 Professional Cylinder Assembly by Michael Tucker

As all the 'fake brand' reviews are below I settled on this German made Delco AC part. First time works. It's a problem for "Desktop" because it has 4 outputs instead of 2. It doesn't come with a bench pump kit so I had to buy one. You can slide the cylinder in by hand so you don't have to clamp it in a vise. I bled it in the car because the hoses came out and dripped when I installed it.
