I have a 2013 TC and want to install a Webasto Air Top 2000 STC Gasoline Aux Heater. My question is: What is the best way to pull gasoline from the fuel system to run the heater. I had a Sprinter, which had a nice factory aux fuel port near the tank, but have not been able to locate any information on such a thing for the TC. Thank you if you have any suggestions.
The Webasto installation instructions state:
"7.1.2.Vehicles with fuel injection engine
When installing the heater in a vehicle with a fuel injection system, it is important to establish whether the fuel pump is located inside or outside the fuel tank.
If the fuel pump is located inside the fuel tank, fuel can only be extracted from the return line using the Webasto fuel extractor (Fig. 8). In this case it is necessary to ensure that the return line extends almost to the bottom of the fuel tank (otherwise the Webasto tank extracting device (Fig. 9, Fig. 10 and Fig. 11) can be used.
If the fuel pump is installed outside the fuel tank, the fuel connection can be made between the fuel tank and the fuel pump, again using only the Webasto fuel extractor (Fig. 8).
