Oil Plumbing Fun
In a Hayabusa, the cooler sits inches away from the engine, so the oil iines are short. The ends of the lines are two-bolt flanges with O-rings in them. Not an easy thing to find replacements for. If the car was still at Tim’s shop, he surely would have made some billet adaptor to use A/N fittings or some such nonsense. Since this part was happening in my one-car garage, I solved the problem with a hacksaw.
The permanent-looking crimp-on hydraulic hoses can me made un-permanent with the careful application of cutting technology. Simply cut the crimped bit without cutting through the pipe below and you expose a simple 1/2″ barbed fitting.
GoodYear 300-psi 1/2-inch hose is only about $3/foot and laughs in the face of the simple job of being an oil cooler hose.
Not knowing how much I would need, I shot big and bought 5 feet of the stuff. Turns out that wasn’t as excessive as I thought. I used every inch of the hose. The Hayabusa cooler mounts very easily to a couple of aluminum bars bolted to the stock A/C evaporator mounts. The few inches of hard pipe on each of those Hayabusa oil cooler fittings point the hoses in awkward directions, requiring this bosozoku-style hose loop, but nobody will ever see it hidden behind the bumper.
