We've been using the Gulf Coast F1 paper towel filter for 15 years (3,000+ hrs) on MOJO. Can't say enough good things about it! Fuel stays clear and bright pink, and no need for Bio-Bor, etc. We use a 12v Walbro pump. One word of caution - Gulf Coast say your flow rate should not exceed 120 gph (2 gpm). I let mine run 24 hrs on each of our 4 tanks once a year, and filter fuel through the Gulf Coast filter whenever the engine is running (200-300 hrs/yr) The paper towel filter gets changed every couple of years whether it needs it or not.
