I do not want to be rude...
But
Specs are not really interesting, as there is only one that will work on your webasto thermotop V or EVO.
Webasto DP41 pump (diesel)
Because the software checks if the right pump is attached before the startup sequence is started, it makes no sence to look for another, it will simply not work..
It is also a dosingpump... so the flow rate is not like an ordinary fuelpump, but the pulses it gets from the FBH, determines the flow rate... which differ and depends on the Fase it is in and the heat needed..
Every other dosingpump, has a different flow rate... so if you use the same model pump, but a different type, like one meant for a petrol/gas thermotop, it will get the wrong amount of fuel..Best regards
