1) Use a flat blade screw driver and carefully pry off the Oetiker clamp that attaches the fuel line to the spout. Be careful not to damage the plastic spout. I used a Dremel tool with fine grinding wheel and slowly cut through the clip until it begins to split, then pry it open with a screwdriver.
2) Push the filter into the spout. It is a pressure fit, so push it in until it stops.
3) Reinstall the fuel line with a the Oetiker clamp that came with the filter. For this you need to use the correct tool or purchase a pair of pincers, Autobahn $15.
