I got the factory type quick connect fitting in the post, ( I had shortened the line but lost the original fitting which I was going to push back on, hence the mod) removed my mod and pushed the new fitting into the nylon line.
So now my fuel pressure block has return line outlet pipe identical to inlet pipe and inlet and return nylon lines clip on with quick connect fittings.
I used a pipe flaring tool and caulking gun to push the fitting on to the nylon fuel line cold as I have seen on a few youtube vids, worked a treat but swearing helped alleviate the frustration of doing it in situ on the vehicle.
Of course it's a landrover so wouldn't start after !! [bigsad]
But that's tomorrows job.
