Diesel heater fuel pickup

So I bought a diesel air heater for my L400 and wondering about plumbing it into the vehicle’s existing fuel tank.
It comes with a small fuel pickup (see photo) that I would put in the bottom of my fuel tank, but I’m wondering if it create too much vacuum inside the fuel tank since I won’t be running the vehicle’s engine when using the diesel heater.

Is the gas cap or tank vented on these vans???

Can't speak for the L400, but a common method when installing a diesel heater in the L300's is tapping into your fuel is by plumbing a 3-way valve into the hose destined for the fuel filter. This could me a viable alternative to your fuel delivery questions.
