For my first Instructable, I'll document the steps I took to install a secondary fuel filter in my 1983 Mercedes 240d. Currently I'm running a mixture of WVO and biodiesel. My fear is that I'll be on the road and have to do roadside maintenance because of a clogged filter- now I don't have that problem.
*Please note- if you try this, you do so at you own (and car's) risk.
Step 1: Tools and materials
razor blade, or knife
something to catch the fuel that spills
Fuel filter- I used a Mann WK 842/3
***3/16" fuel line 4-5 ft***
In line fuel shut-off switch
(x2) 3/16 T-connections
-small: enough for all hose connections
-Large: To attach to optional mounting bracket
custom mounting bracket (not discussed in this instructable)
***If you're running WVO or biodiesel, you will want to get synthetic lins such as Viton or A1 grade Marine fuel line.***
