I'm planning on changing the fuel filter on my car (90 300se) in the near future and would like to change out all the fuel lines near in the vicinity because some of them are cracked and will probably fall apart when I touch them. I looked in the fastlane catalog but there's a whole bunch of sizes listed. Does anyone here happen to know which sizes are needed? If I need to get several sizes, then I might just let the indie do it, cause I really don't need a spare 25 meters of hose laying around Also, is there anything down there that I should change while I'm at it, like the fuel pump check valve or accumulator? Thanks!
