BoostmBenz,

And just think of all the tiny particles your filter is passing thru that it wouldn't pass if it was partially dirty. Think of it, the filter filters out the tiniest particles just before it is at the point where the holes in the filter medium will not pass the fuel molecules. That's when its time for a new filter.

Rderton replaced his primary filter at exactly the right time and does NOT need to replace the spin on filter.
