Even if you've never heard of anyone doing that. The main thing is that it is CLEAN.
yeah.... likely it would work out just fine but it would make me nervous. On my Cummins, supposedly it is self priming. The procedure is to key on the engine for 30 seconds, and then off. Repeat this 5 times and the new filter should be filled and bled. I will know once I actually try it out.
