2001 gtx di hose locations

[Dtracer508]

hi guys so I bought this project 01 gtx and it came with a brand new sbt engine in a box. I’ve about got everything hooked up but have a few questions on where these hoses go. The first picture I’m wondering what hose connect to the 90 fitting on the bottom of the compressor. The second picture I’m wondering where this hose runs too. Third picture there is a fitting on the air cleaner, does a hose go here? Thanks!

I believe the 1st and 2nd connect together. See this discussion for reference: 2004 sportster 951di, line routing on compressor question

The 3rd picture is for fogging the engine. Nothing connects there in normal operation.

No, they don't connect, they both go back to the oil tank filler neck. The first is the oil return from the air compressor and the 3rd pic is the vent to the oil tank.

The first connects to the bottom port on the neck, 3rd to the top port.

The fogging port is on the top of air box and not seen in the 3rd pic.
