I ordered some of the napa/dorman hose, should be in on Monday. No stock of any size to even look at.

Maybe my fan was just crappy.... But I installed the fan and the hoses. Pull the heat lever up to activate the fan and I can feel the flow, but it is kinda like the breeze you get from a screen door closing.
Not worth the amount of time or space it takes up in the engine bay. So I just use my foot at a stop light and get up to about 2000 rpm and stay warm. Does anyone find this fan option even works? |

@malcolm2 Both types of older hoses can crack, get dented or leak over time and many repairs and hands touching them. You might need to do a quick review of the system, follow the hoses. I had a big hole in the tube under the speaker I did not see for a while. You can take the hose off the blower in the engine bay and see how it is working, mine moves a lot of air.

i must have had a weak fan. Hoses were new and operational, fan was purchased used from here, and it did turn. whole car had been taken apart and re-worked, no holes in the threshold pipes either. (IMG:style_emoticons/default/piratenanner.gif)
Wonder what kinda flow is normal. |

QUOTE(malcolm2 @ Feb 26 2023, 11:04 AM) Wonder what kinda flow is normal. gale force 2. heaps. sh#tload of air. etc. somethings up with yours. as you pull the heater lever on the floor up, you should be opening the flaps in the heater boxes at the front end of the heat exchangers gradually more and more. cable operated from lever. this lets the hot air from the heat exchangers through and up the longs. its not until you pull the lever fully up that the fan kicks in. its a boost fan for low revs. like sitting at the lights. normally at higher revs cruising the engine cooling fan which is also connected to the system is providing sufficient air flow to push the air through the h e s and with the lever partly up to open the flapper valves to heat the car. the air flow from the cooling fan comes off two little valves with flaps the are off the side of the cooling fan casting on the underside and join to the h e. not all type 4s had this engine bay boost fan. i've seen a couple of south african 411s years ago that were in australia. did not have the engine bay fan. hot climate car delete? |

I think what I've learned here is that my hose is special and I should be gentle with it. (IMG:style_emoticons/default/biggrin.gif)

Sorry to reopen this, hopefully we don't get to 6 pages! Did anyone ever find a part number for the bracket? How do you get a part number for something not in the PET?

How do you get a part number for something not in the PET? go to page 2 of this topic. i posted up the pages from VW 411/412 parts book. its there. you can see it in illustration its a VW part. shared with 914 or borrowed for 914. they seem to have just used the circular strap and not the T hanger that went with it on the 411/412. but you won't find it. no aftermarket for 411/412 and no VW spare parts for 35+ years. except in a junkyard. i hope this doesn't flick it over to 6 pages...........!!!!! (IMG:style_emoticons/default/biggrin.gif) i would suggest what is called a stand off clip or stand off bracket. commonly available from specialist plumbing suppliers. used to hang fire services pipes in buildings or other plumbing pipes which have to be stood off surfaces a precise dimension. often they have separate adjustable ht t fixing brackets that clip screw or bolt to the circular pipe strap. look them up on google. ie this. https://www.bunnings.com.au/kinetic-50mm-he...2-pack_p4920109 a spacer fitted between where you bolt fix it will let you adjust overall inner diam to suit hose. the one i have linked to is pretty close 50mm. |

How do you get a part number for something not in the PET? Did the NAPA/Dorman hose show up? and working ok Picked the hose up. Looks like it will work fine. Smaller ID is a bonus over what the usual sellers have, 2.25 v 2.5. It is spiral wound v accordion in case any one was asking. The larger hose is harder to mash down with the clamp to get a good seal, not critical in this case but it helps. I have not installed it yet, I will need a clamp to keep the longer hose out of the engine fan, especially after the engine warms up and the hose gets more flexy. It should work fine and look good too. Having said all that, I still prefer an accordion style hose that is more rubber than plastic and a little more rigid. Still looking for perfection for a crappy old race car. Make it make sense... |

QUOTE(930cabman @ Mar 6 2023, 12:25 PM) What was this all about anyways?? @930cabman Info and availability on the exact hoses in the first post. That devolved into what is readily available, then what everyone likes, then what they want, then what they have tried, then what did not work, and on and on with more and more detail. Dangerously close now... |
