Reply To: [How to Tutorial] Change Vacuum Lines on Hyosung GT125R GT250R & GT Comet (Air Hose Diagram)
So if the EGR device can simply be removed, can I remove the T juncture in the Yellow line and just run it directly from the manifold boot to the rear pump? Also regarding the leaking fuel cap. Since it does leak when turned upside down, is this something I need to fix or is it fine as long as I keep my tank right side up and not affect performance
The rear pump will be happier when the EGR is blocked yes.
Feed the rear pump straight from the intake manifold 👍
Tank Cap.
Fuel may evaporate and venting issues might crop up on a hot day sometimes.
Id replace the cap as its not user repairable. Seals tend to stay attached to the cap also.
