I have all the hoses I need for my heating system to be complete...... Except for the blower hose that goes from the heater blower to the J-tubes.

Is there anything I can find at my FLAPS that'll work? I've tried a shop vac. hose but it's too small.

Maybe an old style vw shop...

Carburator heat hose at your local Flaps.

I'd go to Uncle George at AA - he definitely has them & they are correct.

I actually just bought two of those carb preheat hoses today... I'm using them for the flapper to body hose connection. I didn't think they'd be long/flexible enough for the blower though.

I actually used shop vac hose when I was in a pinch; in fact it is still on the car working fine. What I did was place a muffler pipe expander in the tube and expand the hose with a little persuasion from a propane torch to soften the plastic and allow to achieve a new set.

They are still available from Porsche.

I found something that works from McMaster Carr. They carry lots of hose. I could find a number for what I used if you want. It was a little stiff but worked fine.

I ended up finding some stuff at my local VW shop... Heater tubing stuff for a bug I think.
