fuel pressure test "results"
Please analyze my test results. I changed my filter this morning. It was very dirty. Then I took the truck to AZ and borrowed/loan a fuel pressure tester. It took 8 cycles 
of the key to get the koeo pressure from 0 to 62. I then started it koer pressure 64. I turned it off pressure went back to 62. I let it sit 6 minutes pressure went down to 54( I had the gauge on finger tight with no teflon). So what do you think how long do I have on the pump?. Should it takes 8 cycles to build up to 62?

fixed for now.I just tested it again and koeo 62. it went right up there with one cycle. koer 64. I guess the new filter, some injector cleaner and driving it cleaned it up. I bought a new strainer for the pump and i will put that on in a few months when i take the bed off for some other work...thanks for your input
