Looks like these part numbers are for many Volvo cars, so just plug them in and pull up the diagrams to make sure it is what you are looking...

Grab one from the junk yard, new should be pricey. Toss the hose with a flat screwdriver at the engine block, it is stuck on it and needs some help to remove it from there.
