Good morning everyone. I have a problem with my baby. Last Sunday, I installed new fuel filters on my baby. Started and no leaks. Monday night, saw some fuel on top of the spin on filter housing. Tightened the bolt on top and no leaks. Checked last night and it is leaking again. Checked the bolt this morning and it looked like there are 2 orings but no washer. Is there supposed to be a washer there? Thanks in advance.
