Far as I know that's a pump relief valve so I'd check the main pressure regulator isn't stuck closed.

Yes, when I had a blockage at the tank fitting (due to expanding internal 'O' ring in the fitting closing off the fuel flow) it spat loads out of there due to having nowhere else to go.

Dumb question, do you have it connected to a circuit (ie throttle body with the return) or are you bench testing it with only the outlet connected (ie straight to a pressure gauge)? If you were running it without a return I'd imagine it would back up when it pressures up.

No, its in the bike . Put all new neoprene fuel lines in 2 days ago. New fuel disconnects good filter ect. No obstructions in the fuel lines.
