I have a TMX IO-360 engine that I ordered with a hollow crank. It is
mounted on a RV-8 that is getting close to flying.
I am hanging a Catto (fix pitch prop) on it.
The engine is fitted with a stainless steel oil line that goes from
the nose of the engine to a pad of some sort to which the prop
governor would be mounted.
It has been suggested to me that I need to remove that oil line can
cap it off, since I will not be using the governor.
What or your thoughts on this. This is the first that I have heard of
doing this.

Hi Dale,
Oddly enough, I have exactly the same setup, down to the propeller. I am a few months from the DAR. I understood from Mahlon that it stays were it is. I was unclear if I might want a constant speed prop at some point and ordered the engine that way. Be interested in what the actual experts say about this but as far as I know, Mattituck sent the engine in the correct configuration to run.

Dale,
Actually, leaving that line and the adapter for the governor on, will allow you to NOT have to remove the front plug from the crankshaft to pierce the rear plug. Piercing the rear plug [and replacing the front plug] is normally necessary to allow the pressurized oil in the crankshaft a place to go [when not using a C/S prop] That pipe gives the pressurized oil a way back to the crankcase, without having to remove the front plug and pierce the rear. This will come in handy if you ever change your mind and decide to install a C/S prop.

Yep. Same arrangement I got (and paid for) from Mattituck. Not sure who is suggesting you need to rip it out but stop listening to them. :*)

Hi Dale,
Congratulations! This is my understanding as well. You remove the line and stick a plug in the hole if you are not going Constant Speed.
Good Luck!
Bill.

A couple of thoughts. I started out with a FP prop on my 8A. After 350 hours I put on a Hartzell blended airfoil prop. The performance change was huge. If there is anyway you can go with a CS prop, do so.
If you stay with the FP prop, you do want to remove and cap off the governor oil line. As discussed in the Lycoming Service Instruction 1435, to mount a FP prop you need to remove the forward crank oil seal and then pierce the rear crank oil seal. Once done you replace the forward crank oil seal (with a new one - available at Van's and other places). This to allow oil coming into the space between the oil seals from the journal bearing to have a path back to the sump. This prevents the forward seal being blown out from pressure buildup. Removing the pipe and capping off the ends just eliminates an oil path to this between the seals space.
Save the pipe, it is very expensive and you may want to shift to a CS prop someday like I did. Reversing the process requires you to replace the rear seal. Not hard if you have the right tool. Real easy to damager the oil return tube if you don't have the right tool.
No matter what however, follow the Service Instruction. I would expect your DAR to ask you if you did or not. http://www.lycoming.com/support/publications/service-instructions/pdfs/SI1435.pdf

Carl,
I would suggest that you go to the Lycoming List post linked below. [It is the start of the thread]. Read this post. Scroll down and you will find links for each continuing post in that thread, so that you will understand that there is an ALTERNATIVE way of allowing the oil to drain back WITHOUT removal or puncturing either plug in the nose of the crankshaft.

The answer that I got from Michael Yousik (of Mattituck) is "leave the
line in place" because of the plate that is installed on the governor
pad that allows the oil to be dumped into the sump.
See the photo attached to see the machining that was done to allow this.
