I am going to change my filter tonight and need some tips, this is my plan, remove the top, what size socket is that? lift the filter out and let it drain back into housing, replace filter and o ring, put cover back on, How tight? then bump the starter, when I do this do I take the key back to leave it in run position?, do I need to wait for the light to bump it? What am I missing? Sorry about all the questions but his is the first thing I will have done on my new to me 01.
