are you going to run it via hose to ports or tubing?
the latter requires : port bracket, qr shut off coupling 3/4, push fit 3/4 thread
1st option add to shopping hose plug and straight through.

I would use

1 x Quick Release shut off coupling with 3/4" male thread.

1 X slimline steel locknut.

I would then order

1 X Brass hexagon 3/4" female nut and 1/2" hose tail (flat seat) complete with leather sealing ring.

That will sort out the van port side if you are using ordinary 1/2" hose.

From van port to hose reel.

1 x Quick Release metal hose plug with 1/2" hose barb.
