Pilgrim's Progress

[Howard2x4x4]

So, Howard, in beautiful West Michigan... as I stand corrected, I don't have the luxury of going out to my garage anymore to take a look-see at something to answer a simple question such as yours, "what is this hole for?" My bronco as you may recall is at my daughters house which is ~10 miles away.

So I looked through my archives and found a photo of when I was dropping a new motor in the bronc quite a few years ago. I zeroed in on that area, zoomed in, and this is what I saw.

The hole in question is still a mystery to me (in the yellow circle), but in this case it appears to have a stud protruding with a nut on it. What is on the interior of that is what I will find out if noone else here cares to disclose that sensitive information. The yellow arrow points to the heater control cable that enters the engine well off to the upper right of the heater box.

Greetings from beautiful Vancouver, Washington.

Ain't no doubt about it, Mark, you got it goin' on! Merits an 'A' for effort AND a participation trophy!

I'm thinkin' one of these

may well be for a manual choke cable.

Although that ship has sailed, I knew I had them somewhere!



Better late than never probably does not apply. Sorry Gnsteam.

On mine, the bottom hole is a firewall retainer, top one is for the heater valve. I don’t have a manual choke.

Thanks Slowleak, I will follow your lead.

Nice! What did you come up with for the filler tube and vent hose connection? Did you just cut the original end and connect them with a hose?

 

[Howard2x4x4]

Now THAT is a good question ba123! I have been pondering and searching and researching and even considered asking a Ouija board. I am glad you askd because my plan +/- could use some exposure and, hopefully, some input from the gurus, poobahs and wizards that hang out here. To begin with, I am using the stock 13 gallon tank with a rubber fill hose and a rubber vent hose. The Hagen door comes with a tee sorta fitting to be cut into the fill tube near the gas cap for venting purposes. That fitting was hiding somewhere when I was fabricating the filler neck. Btw, I had to figure out a new tank mount strap, I think because of exhaust pipe routing. Yeah, that's the reason.

I ask because I was trying to figure this out as well. Note that I started my project over 20 years ago and the stuff may have changed in that time, and I also threw out my stock filler tube (not wise) thinking I would figure something out better when I got there...

I am close to being there and I searched for solutions and couldn't find any good ones that would work better and also allow me to use the filler vent, which I think it important. So, I bought a new filler tube (pretty cheap from Graveyard) and was planning on cutting the end flange off and trying to flare the end for a hose connection or figure out a way to put a hose on there...My thoughts so far are maybe an aluminum coolant hose end or maybe try to make a barb/bubble flare sort of end using an exhaust pipe expander with a cut ring so it can expand or something...maybe we can figure it out.

I have been following this thread https://classicbroncos.com/forums/threads/gas-tank-vent.303157/ and it has given me an out-of-the box idea. Think I will run the vent hose into the rear inner fender and adding a marine vent like this one. I think it will suffice as a vent, my concern is gas odor in the cabin. Poobahs, gurus and wizards, what say you?

Hmmm....

I've thought only a tiny bit about that and makes sense to add a valve, but I think those are made to thread into the tank and I'll look when I get my bronco back from paint, but I don't think i have a threaded vent. Might have to use something like this inline one: https://www.summitracing.com/parts/tnk-vvr-il
or this remote one:

Not sure if that one you post has a valve for rollover to stop the flow.

Not too late Lane. I'm also gaining good information from the fill tube discussion. Good stuff!

 

[Oldtimer]

Need to do some research now on what the rest of the holes may be for.

My 68 had no firewall insulation so there are no holes for the insualtor retainer rubber plugs.

 

[Howard2x4x4]

Thanks Oldtimer!

Will you adopt me? lol

Here is the tee fitting that came with the Hagen door. Looked to clunky and cumbersome and wasn't mentioned in the instructions.

At least you got a tee fitting…I got nuthin. That’s fine though as long as my cut filler tube works…but liking your idea as well.

Actually, I got two of them. I misplaced (or lost or forgot about or didn't understand) the one that came with the door. I was bemoaning my gas door circumstance on CBF and Yeller (Guru of the gurus) came to the rescue with a link to where an identical vent could be purchased. Need one or both? Just say the word!

You're awesome! I might have to take you up on that. Let me get to that part once the Bronco is back and I'll let you know.

Thanks!

I promised a pic of mine when I could.
