After looking at the pictures again it appears that in this particular system, the outlet on the header tank is on the bottom rather in the side with a drain on the bottom. This particular tank is not appropriately designed to act as a water trap in the system and the gascollator is a must.

Hey my model 4 has already been switch over to Tri-grear.
I don't even know if I have a low spot in the fuel system anymore as the plane sits level on the ramp.....

If you have a Tri-gear, where did you mount your gascollator?

That is correct.
