Show me your heater blower Y splitter set up Options

[DC_neun_vierzehn]

I bought AA's heater blower update kit with the Y splitter and installed it over the weekend. The hose that goes over to the passenger side is very long. I'm interested ins seeing how others have that hose secured as it goes over the engine from the motor to the passenger side.

I'm guessing zip ties are used? My fear is that having it loose and flopping around in the engine bay, it could get sucked into the cooling fan (and it just looks bad).

If you have this set up, please kindly share a pic of how you ran that hose from the motor to the passenger side?

70-72 cars had the centrally-mounted fan with outlets on the left and right of the housing, just like the 411 did.

73-74 cars had the single-outlet fan off on the left side of the engine bay, with only a single hose connecting to the driver's side heat exchanger.

75-76 cars had the same fan, but had a splitter attached to the outlet of the fan, and had one hose going to each side.

documented quite a lot of 75 1.8s for the L jet research.
a lot of what appear to be still very original cars.
all running the single hose fan as per 73/74.

about as many pop up with the twin hose set up as they do for 73/74s these days in well documented sales info. makes me tend to think its a later mod.
i recall old sales ads in VW magazines from the 80s the kit was around then to do the twin hose set up. a lot of cars are likely to have been modified during that time?

however its entirely possible that porsche or VW in 75 thought of a way to use up stock of 412 parts left over when 412 ceased production in 74. it could have been a dealer thing to install. def it would appear to me that the 75 L jets at least had the single hose fan as standard from factory. got a lot of examples on file.

can't speak for 2.0 L cars. were not researching and documenting.

its also a very tight squeeze to get it in under the charcoal can on the 75s.
i have noticed that the cars that have the two hose set up appear to have flipped cans where the owner or installer has mounted the can upwards of the battery tray rather than downwards.
