What all hoses are needed during a 24v swap???

[Overlord475]

Trying to think through all the hoses needed while doing an S50 swap.

Obviously Coolant hoses, but what else??? Fuel, vapor return, etc… Also whither they are S50 or M20 specific.

Been looking around, but this seems to be one of the subjects that gets skipped over in most write ups.

Specific to setup depends on your mix of parts for instance if you have an e36 steering rack then you could use all e36 hoses for that system.

Fuel- Send and Return both use 7mm id BMW Fuel hose IIRC.

AC- in and out to compressor most common is adapting the e30 lines to the e36 compressor.

all of this is very common things to run into for all swaps, most can be solved simply with a hose from either the donor or the recipient, I prefer AN for some systems b/c it reduces the vehicle specific parts needed on my shelves for spares.(though cost is generally the same or slightly higher)

Fuel is 8x13mm metric hose, or 5/16" fuel injection hose from Auto Zone will work as well (marked SAE 30R9, $5/ft).

The evap system will use hose from the E36 to activate the E36 charcoal canister valve, which then goes to the E30 canister.
