I'm going to install one of the Prestone flush kits in my 1998 GXE. For those who are unfamiliar with them, they are just a plastic tee with threads for a garden hose, cap and clamps that you place in the heater hose that feeds the heater. I used one on a high-mileage Camry daily driver and it did wonders for clearing out the crude and made the heater much more efficient.

My problem is that I'm not 100% sure which hose feeds into the heater. I think it is the upper of the two hoses based on the FSM schematic but I thought I'd check with you guys before I start cutting anything. Here's a pic:
