<p>The invention relates to a pump, in particular for a fuel injection system of an internal combustion engine, said pump being connected to a high-pressure region and a low-pressure region. The low-pressure region has a feed line and a return line which are connected to the pump (1) via connecting pieces (5a, 5b), each said connecting piece (5a, 5b) being sealingly inserted into a feed opening and a return opening on the pump (1). According to the invention, a connecting piece (5a, 5b) is provided which can be used for a feed and for a discharge for a fuel injection system, a reliable sealing connection to the feed opening and/or the return opening being producible with an inexpensive production using said connecting piece. This is achieved in that the connecting piece (5a, 5b) is made of a plastic material, and the connecting piece (5a, 5b) is surrounded by a sleeve (9) in the region that is inserted into the feed opening and/or return opening, said sleeve being made of a metal material.</p> |
