[B]As far as I know, a new fuel pump comes with a new check valve. If you changed your pump, then you have a new valve.

Hi Meza,
I have a 260E from 1988, changed fuel accumulator, and I am suspecting problem with erratic loss of fuel pressure ( engine stalls for a few seconds while running ) Do you know whether there is a check valve on the pump of the 260E model from 1988 , The engine and equipments should be very similar to those on a 190 2.6

Thanks
