I dont have part numbers but it is a standard pickup tube from webasto itself.
Each webasto truck center should have them on the shelves as most commonly used.

The tube is a 60mm piece of alu or stainless, drill hole, fit pickuptube and ready.

Pom, the schematics of the puma fuel system are out here somewhere on the forum.

You have 2 loops
1 between filter/cooler/pump
1 between filter and tank

You are half right saying there is no pressure but only in the second loop.

The first loop is always under pressure, also the return to the filter. This is where people plug in the T as it is the nearest position to the webasto water heater. But it can become a problem once the webasto in-line pump starts leaking and fills the webasto with fuel. + getting air in this side is problematic.

If you plug into the second loop, you can as well go to the tank directly as you are that close to the tank already.
If you T-off into this return line you will suck dry air if not on a full tank as the pipe does not go deep enough.
If you T-off in the suction line you risk again that the webasto pump will not seal off one day and the puma fuelpump will start sucking air trough the webasto. As the puma fuelpump is not self-priming it is a bad idea to my opinion to disturb this fuel line.

This is not relevant to a webasto. It has to be fed directly from the tank, not spliced into the existing feed. Hence it has its own electronically controlled pump.

sorry Pom the webasto kits come with a plastic "T" to splice into the fuel lines. Both the Land Rover and Webasto land rover instructions show the "T" being used. But like Tatra805 says, it puts alot of pressure on the webasto pump and possibly the heater unit.

cheers Derrick, I will see you at the farm in May, I will also bring the Swiss LHD webasto mounting kit up for you to see. I'm not going to fit it until we move house and I'm going to do a "drop the tank" installation.
