Bosch fuel pump check valve/one way adaptor from Sytec. As supplied with a Genuine new Bosch 044 fuel pump, these adaptors fit straight into the female outlet side of pumps with an M12 x 1.5 thread. This adds a one way check valve onto the front of the pump, stopping the fuel in the line from draining back, ensuring faster priming of the line up to the fuel rail. Once fitted you'll need an M12 banjo, sealing washers and cap nut onto which you can connect your fuel line. We offer push-on banjo's in 8mm, 10mm or 12mm, as well as -06 and -08 JIC males for proper female fuel fittings, see them below in the list of associated products.
