Couple questions:
"I first put Seafoam each check valve by dumping it in through a hose with the check valve hoses temporarily removed"
so you disconnected the upper hose that connects to the back of the pump, and ran a smaller hose to each check valve to fill it up with seafoam? How seafoam would you say to use?
Also - I have a cold start delete as part of my tune.. I don't have this start up sequence and my pump won't start at all. How is the ECU picking up P0411?
Thanks.
