Your engine will burn warmer fuel, your mpg will go down, and your engine will not be happy with you. Only bypass it if you are in weather cold enough that gelling may present a problem. What kind of cooler are you using?

Sounds more like an ECM cooler than a fuel cooler. If it is an ECM cooler you might hurt the longevity of the ECM. Not familiar with Cummins tho.

The fuel running thru there is cooling your engine ECM. Why would you want that to run hot? Heat kills computers.
