What have high boost people been using to join the extra fuel hose to and from the swirl pot to the standard pug lines?

I know you can get an6/8 to quick connect joiners but I am not using fancy an fittings, just normal fuel hose.

Don't really want to have to buy barb to an6 to then an6 to quick connect as it works out at about £15 per connection and I need 4 lots.

I can't seem to find a quick connect to go to the o.e joiners that used a barb end for normal hose.
