Damn, glad I watched this. Been dealing with this issue every time it regens and it was throwing me off. I must have missed the reset all component as well. Smh. Thanks.

Do you have the parts numbers?

I'll look to see if I have the P/N's still. Also using the Cummins Quickserve Online (QSOL) will allow you to look up part numbers, but may not show the Manifold. I do have the Manifold part number I can post a little later.

I'm getting fault code 1963, what that be the same thing? I've changed the solenoids on the block and still won't regen and cel is still on? After treatment fuel shutoff valve mechanical system not responding or out of adjustment. That's what it says. Thanks in advance! 😎
