the vaccum that goes through the thermo wax, do they need capped?? im removing the rast's nest also and keeping the thermo wax because of the weather around here. so do i need to run the vacuum through this(thermo wax)?

 

You need to cap the nipple where that vac line connects to the manifold. You don't have to cap the nipples on the thermovalve itself.

 

thanks! all i needed to know!
