I have been lucky with the fuel systems on my two ....I heard but have not conformed that just 5% biodiesel added to the new diesel returns the lube properties to the old diesel levels......I get free used high quality cooking oil and it is so easy and fun to make the biodiesel that I run.... anywhere from 50% to 100% in the summer......I am going to put on a big Caterpillar fuel/water separator just for peace of mind anyway....
Keep a can of that canned air with you and if yours does it again...just disconnect from the clear filter and blow back to the tank to see if that clears the screen....
Barry1234 has good advice about removing the fuel cap before blowing the line.....
