CM871 poor power and fuel econ

[Grounded Pilot]

Well dang! Was hoping that was the issue! I pulled the fuel out of the compucheck fitting on the underside of the bottom left corner of the IFSM, is that correct? Or do I need to check the return line?

I have to get some different fittings and I’m going to do the coolant sleeve leak test and see if I have a injector sleeve leaking. I watched the coolant level closely all week and if it lost any, it was a very small amount.

Thanks!!
