Have seen truck struggling on fuel it came out ECM cooling passages was full of this shi#t.
You can take sample to the lab.

Do you know by chance what should be the flow rate on fuel, measured at the quick connector
on engine mounted filter.(cm 2350)This quick connector is getting fuel out, after the cooling plate and before filter and initiate full flow on the gear pump.
I am getting out 1 gal. for over 1 min.
Thanks for the response!

No I don't know the exact numbers.
