fresh air parts?

[orangecabriosuper]

I have a 1971 1302 which seems totally stock and complete. The connection between the vents and the airbox are made by big thick felt things (no snap connectors just make up whole with cotton cloth on the outside and inside) which look original (i.e. they look like they are 50 years old!). I have just replaced the vents through the dash (padded dash) because they had biodegraded in the US heat and it has all gone together well. I had wondered about the felt and the holes and someone said it might be to be with sound deadening - seems to me to make sense because the holes would then allow sound out from the ducts into the felt and so reduce the sound coming down the duct and out of the screen vents. As a bit of chat - when I cleared out the broken cardboard out from the tubes from the floor channels to the chicken foot - I looked down them with a borescope to make sure clear and at the bottom I found a 1967 quarter dollar - it is a 1971 car and the car was imported from the US to the UK in 1990, so it shows my heater channels are original!

I'm trying to put the dash back together on my 72 super beetle and I'm not sure if I am missing parts. Specifically, air from the trunk comes into the cab around the base of the air box knobs. Is there supposed to be some kind of seal or grommet around the base of the knobs?

In the diagram it shows item 30 which might be some sort of seal but I can't tell for sure.

Does anyone know if #14 are starlock washers and if they are what size are they? Where can I find this picture with parts name?

Can anyone tell me where to find the rubber flap #23 that goes in the fan housing or how to make one?
I took my air box apart and both flaps are hard and dried out, when i touched one of them it broke apart...

Thanks :shock:http://www.artsurveyor.com/samba/1972_sb/fresh_air_vent/fresh_air_box_late.jpg

When it's snowing, it never touches to my windshield when I'm driving like 50 mph, there is a pocket of air that prevents the snow to touch the windshield..

wow.. the area where the fresh air intake is is almost in a vacuum no wonder they added the fan. now if you had a longer scoop that opened mid way down the hood and everything was sealed up you would be getting some massive airflow

I had one of those hood scoops and it dosen't help as much as you think. It does increase the flow, but it's more for looks.

Thanks Tele68...called Mid America and ordered part #301-974 Power Vent Duct insulation $14.99 (pair).
Will also try the 2" vinyl tube. Right now I have milk jug plastic wrapped and taped around the two pieces...gives a good tight fit, but a pain to undo and work in those areas(left or right side). My fan works great...but if I could find the HOOD AIR SCOOP that wold increase the air flow.

Just throwin this out there. Trimmed down pringles can covered by left over automotive carpet, all held in place by zip ties. I know it sounds redneck, but it works.

Why are there holes on the pipes that are supposed to transfer air? Also the heater pipes under the rear seat have holes after a certain year. Is it necessary for breathing or ventilation?

I think the cloth covering over the holes is for a muffler effect to make it quieter like the covers on the heat muf under rear seat. maybe

FYI, Mid America has the padded connector sleeves with the snaps and all the correct size aluminum hoses for this set up at reasonable cost. Just did mine all back to stock and it works great, air everywhere...hint, use a piece of 2" vinyl air hose (any FLOPS sells it) under the snap connector for a nice air tight fit, also helps hold the dash vent ducts in place.

Thanks Gary(sorry, I don't know what closed tag is?), Foreste665 and 66Foot.
66Foot, is there anything under the snapped cloth wrap to cover the holes and get better air flow?

your not the first person to be looking for this.
aluminum flex hose (the spiral stuff like for your motor but the cheaper uninsulated kind) can be used along with a clamp and if your fan works you should get better airflow especially if you find that scoop.

The original piece is four or five layers of thickwool cotton like is used for dampening hifi speakers. it had a push snap like for childrens pants pressed into each corner to hold it together.

it is more thermally insulated but it does leak and the hot air gets blown into part number one anyway so theres no thermal loss issue. if there was any loss it would only be a factor in the summer where it would be welcomed.
