i wouldnt have 1/2 " hose on the pump,
id have a small lenth of 1" hose connected onto the submersible pump, permanant. jubilee clip.
then when needed to fill van tank up id add the other 1" lengh of hose to the bit on the pump to feed into van water tank.
id do away with the 1/2 " hose all togeather.
we can easilly get used to going to wilkinsons etc to get some fittings.
im just not used to these fittings.
ill check them out.
any link to which 2 id need. male/female, or how do they connect.
