Ive got cars running these for years.
I had a kid show up to my house in a turbocharged S2000 with an aluminum T screwed directly into the head, and the Oil Pressure sender AND Turbo feed line directly on it. I noticed his car was leaking oil onto my garage floor. I poked around the engine bay, found out his T was cracked. He started the car and the T straight up snapped off.
T Grease gun hose got him back on the road.
Any Auto Parts store or even WalMart will have the hose. Theyre available 6-24"
