I am in the process of doing my first annual inspection on my RV7. I am removing all the panels and so far I have not see any type of fuel filter in the system. I do have the electric fuel pump between the seats on the lower console. I checked all the previous logs and do not see any mention of it. I am used to a gascolator in my Husky. If not it sure looks like it should have some type other than the one inside the fuel injection system.
