OK - so the epoxy patch didn't work, it's still pouring out. There must be other fractures further along, and I just can't access the line in that location. Looks like it's going to have to be towed / trailered to a garage
The line which has gone is number 2 in the enclosed diagram, which looks to be the return. I've also read that the coupling at the engine end needs a special tool to disconnect it, can anyone shed any light on this?
Thanks
