Just to update this in case anyone stumbles accross it it in a search. I haven't got the final answer yet, but the runner filler hose, when flipped end for end, ends up quite close to the PU filler hose. Just have to work out a connector.

I also need to get a longer high pressure delivery hose. The runner had an access hatch that allowed disconnecting the hoses, so I need longer hoses that will let me drop the tank before disconnecting them....

The fun never ends
