I didnt thou mate thats the thing

It was the pipe inside the tank not the outside so no fuel pissing out anywhere. theres a tiny little plastic bridging thing that goes from the pump to the metal pipe that comes out of the tank to the rubber fuel line!! like some sort of mini reservoir, can post a pic of it when i get a sec to take 1.

There was fuel getting into the rail, but eventually worked out by disconnecting the fuel return pipe to the tank on the bottom of the regulator there was no fuel flowing back out so obviously not enuff pressure coming from the pump!! thought it was gonna be a knackered pump but i saw the perished seal and temporarily bridged the connection swith a fuel pipe and it started spot on
