Christen fuel pump 844 Szie of Fittings Manual

[MartinG]

Hello Friends,

after finding an auxillary tank ( 15Gal fits well on the front seathttps://www.svb.de/de/scepter-kraftstofftank-duramax-mit-raedern-zapfpistole-53-liter.html
) we now need to connect it to the wobble pump.
Does anybody know the size of the fittings and how to allow the switch to move to auxillary ?
Thank You for Your help !
Martin
