Garage Exhaust Hose

Post by MadMax » Mon Jan 13, 2020 3:13 pm

Howdy all! This is a side topic, but since I’ll be using it with my T, I guess it’s fair game.

I’d like to buy an exhaust hose to run my T in the garage without being gassed to death by the old lady. I see Dayco high temp semi-flexible hoses, but not sure of the size I’d need and if I’d need adapters.

Does anyone use one of these to get the fumes, soot, and Model T ‘emissions’ out of a closed garage? If you do, any suggestions of brand, size, and adapters?

Thanks in advance!

Depends on which muffler you have installed. If it includes a tail pipe then you can just measure it but if the muffler has a oblong hole then the device will have to wrap around the entire muffler. Don't forget about leaks at the muffler bearing (the other end).
Don't expect many to reply to what hose to use as you are taking your life in your own hands.

I got mine years ago from McMaster-Carr. I don't remember exactly what type it is but this stuff looks like it would work. Heat resistant to 500 degrees and it runs about $10/ft. Their part number for it is 55125K73.

Excellent point, Varmint! Hadn’t thought about leaks. CO isn’t a snake to be toyed with!

RV, thanks for the suggestion. I was looking at this stuff on Amazon:

Dayco 63530 Garage Exhaust Hose https://www.amazon.com/dp/B001O4S26U/re ... hEbD9KD1XZ

Something tells me it’s the same stuff as in M-C. Any thoughts on sealing to keep gasses from building in the garage? I would likely still have fresh air coming in as well a CO detector just in case.

If you don't have fresh air coming in then it will create a partial vacuum, kinda like a diesel submarine momentarily running under water.
Winter time we have a kerosene heater running and have to operate it with the door open. The heat and exhaust escape through big vents in the roof, not efficient but at least it's warm and safe.

I would put some kind of fan on the outside end to suck the exhaust outside.

Lot's of good points here. We built a bus repair facility once years ago. We installed an exhaust evacuation system that included a fan at the building wall which basically pulled a vacuum on the hose system. This prevented any exhaust gas from escaping into the room. Also a part of the system was a large spring loaded damper to provide barometric relief. As a vacuum was created in the room it allowed fresh replacement air in. All in all it worked very well even when there were 2 or 3 large diesel bus engines being run at the same time. Of course, with that much air moving in and out it's pretty hard to keep the shop warm.

Today i feel inspired with dumb ideas but would a shop vacuum work with extra hose in and out?? Portable would also be nice for welding? :D Bud :D

I think a fan or maybe a shop vac would help.
It all depends on how long you plan on running a car, how much ventilation you have, etc.
I have a shop that I work on cars for a living in.
I just run a hose through a hole in my garage door with a flap over it. My garage is far from air tight though... I have a piece of PVC that fits inside the hose nicely and I stick it out the door.
But again, I’m not running anything for more than 5-10 minutes usually.

Max, I have an extra hose that is too small in diameter for modern stuff. You want it, pay shipping and it’s yours. (I think I still have it)
Email me if you want it.

I use a Harbor Freight dust collector to vent my sandblaster to the outside. It would work well for exhaust fumes also.

More excellent ideas! I was wondering if the shop vac may overheat? Hmm....

Easy to try and they are like something else,everyone has one? Whatever you use can a meter be found to check air quality? :D Bud. :D

Hey Bud,

I was thinking exactly that. The company that made my security system has a carbon monoxide detector they sell. I’m thinking about getting that out just one from Lowe’s or Amazon.

When I replaced my c/o detector I put the old one in the garage, everything was hunky dory till I fired up the T then all he-double hockey sticks broke loose. Found out real quick that that old one still worked. BOY are they loud. Jim

Hahaha! Something tells me it didn’t take much or am I wrong?

That’s been a thought swimming around in my head - how much CO would get into the garage still even with the hose out the door (and possibly hooked into a shop-vac)? At the same time, I’m guessing the heat radiated from the engine and exhaust would require a window to be open and a fan to pull/push air in/out.

Here’s the set up I use for the sandblaster, saw dust vacuum etc. should work for exhaust fumes as well.

I have 2 exhaust hoses in PVC pipe under my floor. I used 2 gas meter bases with cast iron covers. I just lift of the cover and pull the hose out of the floor. The PVC pipes join together and come up out of the ground out side with a turn down. I do not have a fan on it. If I did it again I would come up indoors and put a fan in and then out through the wall, or ceiling. It works fine as along as you don't run something too long.

That's a really cool idea, Scott. Unfortunately, I'd have to chip up my cement to do that! Ha ha ha.

Many thanks about the offer on the hose, Hank, but I've already just gotten one. Much appreciated.

I'm really liking idea of the shop vac! Something that hit me though... If you were running too rich, would you risk the possibility of ignition when the gas fumes get near that motor while it is running? I'm NOT an electrical person, so I have no clue how independent the air flow is from the motor with a shop vac.

Your concern about unintended ignition is a valid concern. Rich exhaust is combustible. I personally would never use something (like a shop vac) that's not rated for combustibles in the application being discussed here. Way too much can go wrong.

Forget the shop vac idea. Just running the hose out side will do fine. The old filling stations had a hole in the door with a little cover to run the hose out side. Unless you need to run it a long distance. If so, get a small squirrel cage type fan and adapt the hose to it. Then run some duct work, piping, or more hose out side. The fumes will not come into contact with the motor. You are not wanting to collect the fumes, you are wanting to exhaust them out side.

Guy in my neighborhood thought it would be a good idea to siphon gas with a shop vac. The fireball and fire was amazing. Burnt to the ground.

Dave,

Thanks for posting your comment. That's exactly the kind of thing I'm talking about. Sometimes I'm flabbergasted at things folks try. Kinda scary.

Yowza! Hmmm.... maaaaaybe if it’s far enough in the back yaaaaaaard???.... nahhhhh! I think I’ll pass. The mushroom cloud would be cool, but I don’t think my neighbors would be amused. Hahaha.

Seriously, thanks for the input on this. I’m a little nuts, but I’m not crazy. Intuition was working.

One down, one to go!!! :D :D :D

Just dropping a big "thank you" to Dave Hanlon! After I got home from an extended weekend ski trip, I found a boxed up 10 foot hose to use.

Many thanks again, Dave! Have a great week!
