The difference between the Valterra EZ Valve Electric Waste Valves # E85-8 and # E84-8 is the design of the center output tube. On # E85-8 it's a straight, regular hub. On # E84-8 the center tube has bayonet fittings. Based on your pictures you would need # E84-8. However, the input size of either hub is 3 inches so your smaller tubes would not fit without adapting to the tubing size you have up to a 3 inch mating tube to fit the E84-8.

It looks like the smaller tubes are 1-1/2 inch (measure to be sure) so an adapter such as # T1041-1 would be needed. If any of the tubes are different than 1-1/2 or 3 inch let me know.
