You probably got water in there...http://buysentry.com/ will take care of that issue!Yeah and Illinois mandatory b20 blends I'm running 14M fuel water and a 2M fuel filters with lift pump..
Fuel goes tank F/W filter lift pump, 2M filter engine... Lift pump isn't making noise.. But engine runs. But can't go down the road... Bought some hot hand hand warmers duct taped them to the F/W filter says they get up to 158°F
Power Service stuff is Snake Oil. I've had a couple customers that went from that stuff to Stanadyne Performance Formula. (I'm torn between two on the Sentry and Stanadyne). Every single one has seen better fuel economy and cleaner running. The one guy was in BC. His engine missed and sputtered at around 1700 RPM. It still did it after new injectors and fuel lines...he was running Power Service Winter Shit the whole time. It all cleared up after he through a bottle of Stanadyne Performance Formula in.
