This scenario is designed for a fuel pressure gauge after the filter. It will tell you if you are getting pressure to your injection pump, because that is the exact symptom of fuel starvation and the drastic action the ECM takes to protect the pump. Even with a lift pump, a blocked filter will not flow fuel.
Give the man a cigar. Even a cheap $15 Mr Gasket gauge from Advance that you have to pop the hood to read is better than nothing.
A few days ago, I got 5 gallons of crap fuel from a Chevron station in FL. When my fuel mileage went thru the floor and the beast started running poorly, I pulled over into a rest area and checked under the hood. Fuel pressure gauge told the story - one or both filters were getting plugged.
When I pulled the 30 micron prefilter and removed the sediment bowl, I had all kinds of junk come out of that filter - including DEAD BUGS AND GNATS!!!! And the fuel that came out of it also had the added aroma of a hint of gasoline to it.
Word of warning, that station is at the intersection of Hwy 19 and I-10 east of Tallahasse FL.
