Do TJs have a clear flood mode?

"Clear Flood Mode" if you have it is a great way to fill your oil filter if it is one that is upside down or horizontal after a oil change to avoid dry start. Joe
 
This should clear any excess fuel in case the
engine is flooded.

Awesome! I'm glad our Wranglers have this feature as it should also pre lube the engine. I frequently go 3+ months without driving it and I'm going to start doing this before starting it the first time after deployment.
