Yes, the lines are run just like on the canister. Note there is an "in" and an "out"
The main difference between the two mounts I referenced is that one has the lines coming in at the top only, and the other gives you the option of coming in fron either side. Which one to use depends on who you plan on installing it, and what kind of interferences you might have with other parts and how you want to run the lines.
Yes, I know you're working on the 235 right now, but you also have the later 261 engine, so I was trying to kill two birds with one stone, so to speak.
