I noticed the fuel pressure suddenly fluctuate. I barely limped the car home and replaced the 162-558 10 micron filter in the billet 162-558 housing. The filter was slightly off white, but nothing obvious. I also removed the foam and cleaned out the Jaz plastic fuel tank, and cleaned the 162-564 100 micron pre pump filter. The pump is an inline Walbro 392.
The new 10 micron filter clogged up again after running a few more tanks of gas through it. I'm suspicious of the old SS braided -8 hose breaking down although it's not showing any rubber particles in the filter. Or it may be the premium fuel at my local gas station is dirty. These little 10 micron paper cartridge filters seem to clog up easily. Any thoughts?
