First bidder, (if going on to win the auction) will recieve a Bonus Mystery Mercedes Part!!!!!
(I certainly have enough of those around...random stuff that I know came off a Benz, but God only knows which model/year
)
The instructions state that you should install it as close to the fuel filter as poss (duh) and that you should tap into the coolant hose that goes to the heater core. This way, apparently, you can leave it on all year and it won't heat your fuel unless the heat is on. A bunch of pics to show you where and how to do it all and a detailed list of how much/size hose/lines and how many clamps/bolts/clips you will need etc. Feel free to ask about anything else that you're curious about!
