I use diesel fuel from the service station. Do you know how often the big fuel filter should be changed?..I'm sorry I don't know the correct name. I see you're from Long Beach. My ex LA mechanic who is excellent and Very reasonable lives nearby if you'd like his contact info. Do you have a ballpark range of repair for someone to replace this?...In the bay area, the prices seem to be all over the place; most quite expensive.
Thanks
