Connected the fuel lines to the fuel selector. I'm not 100% sure exactly where the selector needs to be positioned. I have looked at many photos from other builders and photos I have from the factory, as well as the build manual for both the Sling4 and TSI. I can re-position the selector quite easily once the dash and center console are installed. Early days the factory installed in-line fuel filters, no gascolator. After talking to many builders I've decided to only use the gascolator filter, no in-line fuel filters in the center console.( fewer connections the better ) If in the future I need to install in-line fuel filters I can reasonably easily.
