Where did the factory route the vent tube? Previous owner routed it through one of the bumper access holes. It didn't clear the front of the front bulkhead and eventually ate through the undercoating and metal. Now that everything is repaired, I'd like to route it where it's supposed to go, but I can't seem to figure where that is.
Hi,
I guess you mean the overfill/vent from the brake reservoir, T-ed into the breather hose from the tank? Indeed that hose went through a grommet mounted in the bottom hole in the front. It should be long enough to pushed away from the bumper in the open air. Valid for my '73, other years I don't know because of the different vent hose route. Hope this clarifies (?).

Hi,
I found an unsued hole in my pan next to the lefthand battery and stuck a PVC drain hose through the hole. It extends a way down as I did not want brake fluid dribbling on my bodywork.
You can see it here:

RSexS -- Do you have a pic of the routing on your '73?
Hi Randy,
Will post that later this week, I am abroad at the moment. HarryD, that works fine, although normally there is a rubber 5 cm long drain plug mounted.

I wasn't satisfied with the idea of letting brake fluid drip out of a hose under my car, and in this case preferred functionality over originality given the damage brake fluid can do. So I mounted a small bottle in the trunk front on one of the bumper bolts and routed the vent hose into it.
No damage since and I don't have to worry about brake fluid on my undercarriage.

It does T into the gas line vent (on my 71 at least), but I totally agree with incher...it would be way better routed into a small bottle for capture to avoid any chance of the stuff getting all over the undercarriage. I'm thinking that's a great little upgrade I'm gonna perform shortly here.

As promised a few pics to show the vent line.
Thanks much, RS exS.
Is that the factory hose? And I see you are in Norway - anyone know if the US cars have this?
Where does this hose originate? I don't recall one on my '73.5 (tho it's in the paint shop and I can't get access to it to see, I think the cap at least did not have any provision for one. Maybe I missed on that was on the reservoir itself...)
My USA '73 has the vent tube running through the grommet placed in the access hole for the front bumber bolts, just like its shown in the blue car.
The tubing available from Stoddard was too short when I looked for it - only available in 1m lengths. So the first time, I used clear PVC tubing from the hardware store. It looked fine for two years, then I noticed it had deterioated to the point that the plastic was soft and bubbly, ready to fall apart.
The next time, I used polyethylene tubing ( more chemically resistant) and it has held up for 5-6 years. I ran it down below the edge of the front bumper so it won't take off paint if it burps a little when the weather warms up. I bought it at the same hardware store. Everyone used to ask me what the tube was that was hanging below the front bumper, as the tubing is milky white. I wrapped it with a piece of black electric tape and now nobody sees it.
Not concours but effective.
Jim
