Yes, includes new coolant lines, and it reuses the factory PS hoses. And am working on a lead for new caps (black to match lol)
Any possibility that the overflow can be turned 90 degrees so its parallel with the line that connects to the upper rad hose?

I can see one problem with this, the factory reservoir also has a filter built in and that's why we relocate them and not remove them.

We used an aftermarket water level sensor in ours and yet to hook it up still waiting to finish the hp28 install.

Your better off relocating the factory PS res to the strut tower and making the coolant tank bigger
to hold more fluid to allow for more expansion especially under high hp outputs.

The factory PS hoses are long enough so there is no need to get rid of it.

I personally like plastic tanks as they are cheaper than head gaskets when they blow, excess pressure has to go somewhere
and the radiator cap bypass is not big enough sometimes.

I do make a larger aluminum coolant res only tank, fits in same area. This tank holds just over 1.5 litres and is plenty for sn expansion tank. . . , And as for a weak point, there are other weak points in the system besides the factory expansion tank

Aluminum expansion tanks are nothing new (except for this platform lol). But hey to each their own.

Alloy expansion tanks are nothing new on this platform and had many offerings including billet ones in the past.

The reason the plastic expansion tank was made this way was its the easiest, cheapest and the quickest to replace and many have realised this and reverted back including myself. BTW the next weak link in the system is the head gasket ask me how I know.
