Techniques for pulling Odorsafe hose?

We're nearing the end of our "change the holding tank and all associated hoses" project. The last thing before actually installing the new toilet is to pull the hose (1.5 inch OdorSafe) that goes from the toilet to the vented loop (inside the vanity.)

My preferred way to pull this 5 foot (or so) hose would have been to duct tape the new hose to the old, and tug. Regrettably, because of the sharp curves in the hose from the vented loop to the tank, I had to remove the one from the toilet to the loop - and now I'm faced with replacing it. I DID leave a messenger line in place, so I've already got a line from hole to hole.

So now I'm looking for good ideas about how to attach a 1/4" (or so) line to the new hose. One thought is to drill a hole in the side of the odorflex, near the end, and put the line into the hose, lead it out the hole to the side, and duct tape it securely. I also think it would help to cut the new hose at an angle, rather than bluntly, to try to avoid the end of the hose getting caught under a floor, etc.

Any great ideas out there? Thanks in advance!

Thanks Hayden! You can't imagine what Sam and I went through last weekend yanking on hoses! Our poor hands and arms will never be the same! Your idea sure is a good one and I think Sam will do this. We have one hose left to do and I'm dreading it. Does everybody think about selling their boats at this point?

Indeed, I do think we will add this - it'll make our lives WAY simpler - for the one time we'll use it in our lifetimes LOL..... Seriously, it's a great idea, and we'll do exactly this. THANKS FOR THIS IDEA, HAYDEN. GREAT CATCH!

Back to the original question, though. Any other ideas for attaching the leader (messenger) line to the hose?

And then, moving the conversation forward just a bit - the boat must have had at least 2 previous toilets. The one we have just taken out was an electric. I suspect that the factory original was a PHII. But there is a veritable plethora of other holes drilled in the top of the step, where the toilet mounts - that don't line up with either the Jabsco electric or the PHII. Go figure.

At the end of the day, the OLD PHII holes are too far back away from the edge of the step. The outlet hose connection is too long to fit there (the one that has the joker valve in it) and have the existing holes line up with the new base. So, in order to use the old holes (existing holes for the old PHII,) I'm facing having to construct a base plate of Starboard, to raise the toilet enough so that the backward slant of the wall will allow me to connect the OdorSafe... The other choice is to have my fiberglass guy seal everything up well, and simply drill new holes that properly fit the new base. I'm not yet comfortable w/ the idea that this second option will give me a good firm base to tap into, since at least one new hole (front, left-most) would be partially in the filler material in the old hole, and partially in the factory material... I've never had much success re-drilling a hole into the side of an old hole. I'd love to hear everyone's ideas about this little detail.

Other than those little issues, the project is moving along nicely at the pace of an injured snail. Will post pix when I finish.

THANKS IN ADVANCE FOR ALL IDEAS HERE !!!

Hayden,
Any photos or more specifics on exactly where you cut the access hole? Thanks.

Replaced all my hoses two years ago. It's a violent project, to be sure. One tip: The hoses are so stiff that you can twist them at one end and the twist will transfer completely to the other end, which helps greatly in removing and pulling.
As for the access hole, I cut mine in the starboard bulkhead. I did not even attempt to put the vented loop behind the cabinets. Instead I mounted it behind the head itself, on the outside wall. I thought it looked cool, but the Admiral made a little fabric cover-up.

Everyone, we have discovered a fabulous find! Raritan makes an odor-safe hose that actually bends! We successfully finished our head project without having to cut any bulkheads.

Thank you AngelFish. I'm getting set to do this project and you've saved me a lot of pain and suffering. fyi: For others contemplating, the product is Raritan Sani/Flex Sanitation Hose.

You are very welcome. Sam and spent an entire summer pulling that stiff hose, so we know what a pain it is. Also, sorry for the typo...I meant "odor-safe", not "order-safe". My iPad plays tricks on me from time to time....
