The dual outlet one. I will add a photo.

its actually a part from a VW 411/412 variant (square back). the y splitter.
if you can find one of those cars (almost as rare as a 914?) in a junk yard and the heater hoses are still there on the engine you could score one.

the 74-76 came with just one hose, left hand side in original form. the dual hose set up on the later cars is not a factory thing its a dealer and owner mod back in the day using the VW part. unique to the variant version of the 411/412.

the 74-76 came with just one hose, left hand side in original form.

In the US, it was the 73-74 cars that only had one hose.

The 75-76 cars used the splitter piece to feed both heat exchangers. I'm guessing that the factory probably recognized that the late-style ones were not as good as the early-style ones.

Not surprising that they used 411 or 412 parts, though. After all, the engine was designed for the 411 in the first place.

ok - i have done a good trawl through the examples i have collected and filed on 75 1.8s.

the blower and hose configuration is definitely another one of those mid year - along the way changes for 75 MY - similar to all the incidental upgrades and changes throughout the 74 MY which did not happen all at once nor at the commencement of the model year.

but first, i managed to find a very well documented 76 2.0 in very original condition that was listed on BAT. a trustworthy example with enough good images to home in close on the dual hose distributor piece. it also had retained its original fine crinkled hoses which added to it being trustworthy with thanks to @914Wes for digging up the VW 411/412 part # for that same piece as fitted to the variant type 4.



you can just read the part # in the image and it matches the VW number from the type 4 PET. except it has an A on the end of it. which simply means its an upgrade part of the original. 461 as the first three numbers means its a type 4 part not a 914 specific part.

the 914 PET does not list this part. instead it only lists up to the 73 - onwards change to a single hose fan. and all the parts listed have the 914 prefix indicating 914 specific parts. no mention of the VW part with twin outlets as can be seen fitted to the pretty trustworthy 76 2.0




i have gone through my files on the 75 1.8s.
i have examples of 08/74, 09/74, 10/74 and 11/74 all fitted with the single hose heater blower set up and matching the 1974 1.8 cars.
this is a particularly trustworthy example.
a highly original in excellent condition 11/74 75 1.8




another example from the batch of 08-11/74 manufacture cars also has the correct 914 seal plug for the engine tin for the right hand side to cover the deletion of a second hose.



given that i do not think any owner would realistically backdate a heater blower hose set up from double hose to single hose and given the cluster of examples, i would say that all the 75 1.8s from 08/74 to at least 11/74 were single hose set ups.
highly likely the 75 2.0s from same period are similar but i do not have data on 2.0s.

the remainder of 75 1.8s i have on file are examples either dated 01/75, 02/75 or a cluster all in 05/75 have the twin hose set ups. a lot have replacement non original hoses which does not assist with verification. but a couple of them still have the original fine crinkle hoses both short and long fitted.

i believe what is going on is that somewhere between 11/74 and 01/75 the cars change over to the double hose set up. i would need to have more examples collected to pin point when but for now i would generally say the cars produced in calendar year 74 have single hose and calendar year 75 have a double hose. and this probably applies to both the 1.8s and 2.0s.

-------

when i think about its probably got a good reason.
they just used up the stock of special 914 single outlet parts until they ran out.
and likely VW had large stocks of the twin hose 412 variant parts still lying around.
production of the 412 ceased in may/june 74 and sales for that car were disappointingly low as it reached the end of its life. its highly probable VW had lots of parts stock left on the shelf and chose to use those up on the 914 - which by that time had also been determined would end production for all intents and purposes at the end of model year 75 (the 76 being a small production run right at the end supplying only the US market).

what i think i might do is start adding this 75 1.8 data i have collected to the end of the topic i set up on the 74 1.8s in the originality section of this website.
i have got almost enough data now to map out the 75 1.8 for any owners who want material to guide them on the 75s.

i don't think its particularly important what individual owners wish to do with their own cars re upgrading and modifying. its just a guide to originality if thats what you are after.
