Yes I can suck the water.

Two thoughts I imagine that might create issues: 1. Energy transfer down due to delta T being lower, increasing the = danger of nucleate boiling near the plugs 2. Creating a higher = differential between the hot and cold sides of the engine producing = increased expansion differences across the engine. Question: Do impeller pumps that we use suck and push equally well? My = guess is that they don=E2=80=99t. If this doesn=E2=80=99t matter would it help with the physical layout to = suck the water through rather than push it through?
