I have the EXACT same issue like he has here (except I don't have any mods yet):

Thing is I have replaced the pump - and the problem stays!
I also disassembled the 0.7 orifice and 3 way solenoid... cleaned the best I could.
Any suggestions?
What is the "pump non return valve" - is it the Neplax viton - part 98120001?
