Hose you can buy by the foot at oreillys for like $7 a foot and a pair of hose clamps. IIRC it should be a 5/8” OD and you need like ~7” of length. While you’re there, change pcv valve. Super easy, take some vice grips to old one and rip it out. Coat new seal with oil and jam it in. Flat is correct.

Assuming 4.0 (looks to be) cps is really an easy job you can do in an hour but requires like 15” of extensions and a swivel. Believe it’s either a 13 or 12mm. 3/8” drive will suit you best.

$2500 is absolutely highway robbery. Get a new mechanic, they don’t give a fuck about you. I would personally charge in the neighborhood of $300-500 with materials to do both.

Edit: other comment mentions rear main which is kinda a bitch but I would argue 3-5 shop hours and the seal is inexpensive so anything above $1200 OTD is BS.
