It did it no matter what level. When we changed out to the Dodge in tank fuel pump assembly, we did not find any residue or foreign materials in the tank but that does not rule this out as the tech only visually inspected the tank. 
Everything now is pointing towards the pressure relief valve in the CP3. I will be looking at that this week.
