Cheers, Mike,

I've just remembered/realised when I've came to take it off. The return pipe was cut down and I welded the connector off the block to my sump (the turbo is upside down, hence a lot lower than the original return). The hose I was using gave up and split. I hope to get some braided line made up and was wanting to know what couplings I should ask for. It seems it doesn't matter now, and just weld any suitable diameter to the return from the turbo.

Thanks for the info on the supply connection, too.

Neil
