Looks the goods @BigSkiddy and it will get a workout down here over winter, its been bloody freezing.
Your kit comes with the tank stand pipe which is good, the Eberspaecher stand pipe must be gold plated. One of the vents in the Aliexpress pic is the return air inlet. My heater is mounted under rear seat of the club lounge. I initially ran the heater without a return inlet and it ran fine, but because I didn't want to throw out the return vent I ended up putting it in out of the way at the other end of the club lounge. Ive checked it with a tissue, no air is being drawn through it.
The pump usually mounts under the van because it has to angle upwards, and the fuel line plugs into the bottom of the heater under the floor. The pump has a rubber mount which helps to deaden the sound. Pump tick whingers must be very very very sensitive .... because its not loud. The Eberspaecher rubber mount is pretty good at absorbing the tick; worst case you get one of those as a spare part if yours isn't as effective.
I have the pump mounted on the large front main cross member of the chassis, which is virtually directly under our fold out bed. I can hear it if I make an effort to listen, but its no bother to me. The Princess (Mrs Crusty) is a light sleeper (and a active and vocal critic. Ha) so if it was annoying I would have been well and truly advised by now.
