Where does the heater (Eberspächer D2L) take off the diesel? Transit Nugget Bj. 91

Hello dear people, today I brought my heater, Eberspächer D2L on my Nuggi Bj 91, 2,5 D, back to life … Drive the Nuggi now 6 years and my predecessor had shut down the heater …. For all those who want to point out this, yes, I know the 10 year regulation. Now to my problem: the predecessor had shut down the heater in this way that he removed the dosing pump of the heater, the pipes were cut, simply let down. l which goes from tank or diesel line to the dosing pump, was removed. Probably there is working with a T-piece there ? Or goes directly to the tank ? I know the thoughtful safety aspect of the D2L, that it only runs with full tank, or minimal half or something, to avoid that one does not heat the tank empty. But that would mean that it is not a T-piece but goes directly to the tank ? Long story short: Can one villt. take a photo under the car n, where the diesel is picked up ? Or describe it well ? Would be great. Dear Gruss Ps: Who asks why I want to know it so “exactly” and not just create a “new” place, is because there are also max. lengths of the conveying lines for the small dosing pump and I do not want to go below it, otherwise the thing may not work.
