H-townbenzoboy,

I was not using numbers to be specific, so 3,000 rpm along with a few other numbers for the exercise were used to make the math simple. The point was to show the amount of Diesel fuel squirted out the injector nozzle each time it squirts is very small. In my haste at 3:25 a.m., I made an error in my simplifying effort that equated to the car getting 60 mpg instead of 30 mpg. The point should still have been made - there was probably not anything wrong with the injection pump, once it was primed, since 1/180,000 of a gallon is still a little bit. In my statement about the 3,000 rpm I was just noting I picked it to do the math and keep it simple, and 3,000 rpm may or may not be a typical highway engine speed, when you are getting 30 miles per gallon.

Jim
