It acts like it is running out of fuel. Have done fuel and air filters, cleaned sediment bowl screens at the bottom of tank and on injection pump. Removed hand pump and companion plug to check lift pump poppets and springs...OK. Electric pump appears to be working. Next step is to confirm supply by teeing into the pump line to see if it will maintain 20-25 psi.
Question, what regulates rack pressure in the pump? Is there a regulator fitting in the banjo bolt prior to leak off pipe?
Same engine as a 4440 if that helps.
