It's shown right on the plans drawing to safety the plastic tubing for the fuel pump overflow/drain tube. But how do you do it?
Got this from somebody. Pull the tubing off and lightly flare the end. You only need a very slight flare. Put the tubing back over and use a small zip tie. It ain't coming off!!!!

I would call bogus...it's right outta the plans, and I can't see a plastic tie wrap wearing thru chromoly steel tubes. I see tie wraps on engine mounts all the time at work...
Use a wrap of good vinyl tape around the mount before attaching the ty-rap.
What happens if this happens? Stream all your fuel out or ?

Okay, I'm not this far along in my build but getting closer, what exactly is the game here? Are we trying to keep the protective outter plastic tubing from sliding on the aluminum tubing in order to keep the aluminum tubing from rubbing against the motor mount?
I had a number of wire ties holding thinks to the engine mount and then my EEA adviser (also an A&P) pointed out that they would wear through. I clipped them off and place under them a small peice of bicycle intertube.

I don't want to hijack anything either.... but is it "OK" to put tiewraps directly on the engine mount? My A&P uses ADEL clamps there. I asked and he said under vibration they can actually wear the mount tubes. Bogus, or real?
Go here and read paragraph 11-96(b) and (o), then read paragraph 11-146, (a) and (b).
Left alone long enough, a ziptie will cut through the engine mount tubing like a saw - dirt and oil gets between the plastic & steel and acts like a wet saw. I just replaced part of an engine mount on a Bell 412 helicopter due to it being damaged beyond limits by zipties holding drainlines in place. It's been just about a year since this aircraft had last been in to see us (it's in for an annual); there were no zipties on the engine mounts when it last left us.
