CM870 misfire under load

[Blackout26]

So, small update. I found a small leak at the fuel shut off solenoid, I disassembled and put new Orings and reinstalled at 49 inch per cummins. Truck ran amazing. Stopped a buddy's house and let her idle for about 15 minutes. Jumped back in and the dead miss is back. Returned home, no leak at the solenoid. Unless I pinched a oring and it is not leaking yet. I checked to see if it had a pre-filter. It does not. I have compucheck fittings on order to dig deeper.
