Well I finally got around to deciding on which dry break connectors and then fit them.
I went with the Jiffy Tite connector even though they cost £100 against £30 pound for the other version in the photo that I got off ebay.
I went with the Jiffy Tite on build quality and a couple of friends have had the other version in the photos for £30 fail, not something you want when dealing with fuel.
FYI.
The feed hose size is 8mm or 5/16 and the return hose is 6mm or 1/4".
The part numbers for the jiffy tite connectors are.
JT 22504P, PLUG 1/4" P/O VALVED.
JT 21504P, SOCKET 1/4" P/O VALVED.
JT 22505, PLUG 5/16 P/O VALVED.
JT 21505, SOCKET 5/16 P/O VALVED.
Well all is fitted and getting the tank of is a lot easier
