Question on this small cooler

[rnln]

Has anyone use this small/straight cooler to replace the oil tank to engine S hose?
If you do, do you remember what is the ID of the port (where the oil flow through)?
Anyone know what is the requirement on this ID?
Thanks.

Update:
Calling around different Hydrolic store and truck/car supplies places. None of them will do pipe/tube that big. One of the guy was nice enough to talk to me. He said, if low pressure, I can get Home Depot brass pipe and use clamp at teh end. I mentioned that if the pipe is straight without grove or thread, will the hose/clamp slide off? He said below 150 psi, it won't push off. If I am talking around 300psi, then it will.
Any pro in PSI and hose clamp can verify this? What kind of pressure I am looking at here? Any opinion on Home Depot thick brass pipe?
How about having Home Depot brass pipe and make the thread on the outter of the pipe for rubber hose to clamp on?

If you want better cooling get a properly sized and flow rated front cooler, fender or valance mount.

The S hose cooler is too small, located too near the exhaust, and not worth it.

I was and still in search of doing something on the real cooler (front or rear) but still have not came up with one yet. Right front fender won't work for me since my car is converted to slantnose and the head light bucket stay right there.
I have on hands a small cooler (maybe 1/2 size of the stock carrera) which will fit there but found out from this board that the ID of the port is too small. It's only 8/10 of an inch.
As for the S cooler which I asked on this thread. I am thinking of geting a staright small cooler or a pipe to replace the S hose because my S hose need to be replaced anyway.
Thanks.
