Does it suck grenade in when it dies? Have you tried running it from a bottle of fuel to rule out a bad supply? If so, remove fuel return host (right hand side) from pump, prime until fuel starts to run out return pipe, then start it and run around and watch how much fuel spills from the return on idle...Report back. also, remove the fuel inlet pipe from pump, and pump grenade, does fuel pump up EASY from the tank? and quickly? If so, and not much fuel is coming out return (video / tell us) then sounds like vane pump.
