All good ideas. I would suggest adding a gauge in the fuel line before the filters to indicate when a filter needs to be changed. I did this on my C310 and it took all the guess work out of when to change the fuel filter.Hi, after my fuel tank became contaminated with bio crap and clogged my fuel pickup (required a tow in) I decided to replace the tank and all hoses. Then I had the bright idea of installing another filter in line so I could operated on either filter while changing the other one. I now am very careful about my fuel. I add Biobor JF each fill-up. Tank was difficult to install and expensive btw. I am now thinking about making a cheap fuel polishing system using the knock off filter.
