Hello Tony and welcome!
Kinda sketchy description, but Iím guessing you had a leaky HydroBoost unit and decided to replace the internal seal that typically leaks. If Iím correct, sure would like to know where you found one, since I struggled to finally score one but was unsuccessful in R&R. It tore
Bought a new unit for a bit over $100 (local auto parts store) and all was well.
Been a while since you posted and seems there are not as many folks weighing in with help these days...
