I was looking for a stage filter when I came across this one. Based on the image and description, I decided to give it a try. This is the new blue style, which is a single stage with a different part number than the old white filter shown. This filter is also loose in the box, unlike the white one, which is sealed to keep contaminants out. I recommend ordering a Racor PFF50216 if you want the older style. br>br>The seller must update the image and part number.
Aftermarket, lower-cost fuel filters don't seem to hold pressure, requiring you to pump it up frequently. After 60 days of sitting, the AC Delco filter maintains the necessary fuel pressure.
For your duramax, the best filter is.
