Fuel filter seems to keep plugging up. Put a new one in last April with a new fuel pump as it went bad. Had the sled start hitting det periodically for what seemed like no reason. After checking other things I decided to change fuel filter again. This time decided to do Mountainhorse conversion to the wix...tired of paying 120 a whack. When I removed the old filter you could hardly blow through it. I cut it open and it seemed like it as all plugged up with wax. Any ideas why it would be waxing up like that? I use only non ethanol premium, mix 1 ounce oil per gallon of redline and mix in 1 ounce Lucas octane boost. Oil and Lucas was recommendation of SLP when I did the stage 4 kit two years ago.
