[QUOTE="mandkole, post: 1259881, member: 4630"] In normal operating conditions (low demand, low temps) the system would operate as a continuous loop going between the LP pump, HP pump, injs. In events of very high return fuel heat (by product of high demand, engine heat rejection, heat caused by pressure), the fuel is sent back to the tank where its mixed to cool. In real cold temps, the circulation loop would be beneficial, avoiding this hot/cold fuel mix can eliminate tank condensation and water production as well. We (7.3 guys) would greatly abbreviate some of the functions on this system. As we would use it, it looks like it would function similarly to an airdog with water separator functions. [/QUOTE]
