I own a 2001 ford explorer sport. I believe I have a high pressure leak coming from one of the inlets or outlets from this part. Been looking all over the internet trying to find out what it is..
Can see it here :

Its a black glossy cylinder (About the size of a 1L bottle of pop) directly to the right of the washer fluid tank.

Thanks
