hissing sound from abc?

Hello guys I hear a hissing sound from under the passenger door I suspect its this little guy https://www.fcpeuro.com/products/mer...des-2203200415

I had the same sound on the driver side and I replaced the abc accumulator and it went away so I think I just have to change out that return accumulator now. Everything else is fine goes up and down fast and does not go down after days of being off.


Video of sound:

The car feels fast tbh ran a 13.000 1/4 mile on a hot summer day in Florida, no brake boost just mashing the gas. when I did brake boost it spun on the prepped surface.
