I am trying hard to get metric so I may be fing up some numbers. If I'm way off in conversion then check me.

If that helps.

Wow, 1.2601 US Gallons /hr @ 2500 that's pretty good less than I thought they would use, quite a lot less.

I really like my cummins. Cause its been well behaved. No odd failure so far.

Good to hear, sound like you made a good choice.

Starts runs and waits. Then it starts runs all over again.

Whats the bolded bit mean?

The bolder part means my phone thought it was important. Otherwise typo. I think if we keep converting metric to imperial and back it will be like free energy. Manufactures have pretty realistic hp to consumption curves.
