335dM, if there were enough room somewhere along the fuel supply system, yes, I would definitely consider a 10/2Ám filter-set like a Racor, but there is not much room under the hood or underside on these cars. I stick with mainstream truck stops for the most part when fuelling up.
CT, what has your fuel supply been like over the 50,000mi? (Brands? Locations?)
