However, we have to consider whether the pump is design to be mounted inside the tank or outside the tank. Fuel pump that are designed to be mounted inside the tank have to be petrol proof. i.e. petrol should not be able to get inside the winding of the motor and cause a spark. The consequence would be explosive to your tank. Another thing to consider for the pump is the flow capacity and head pressure. If the flow capacity is low, then it will not be able to deliver the required amount of fuel to the fuel injectors at high speed. Similarly, the head pressure also play an important part but there should be a pressure regulator to release excess pressure if the head pressure is too high. Hence, it would be sensible to use a bigger capacity pump rather than an undersized pump. However, you have to consider for the constant working of the pressure regulator.So far, the fuel pump is working well but there is nothing like a piece of mind when you used ori parts from BMW (Borsch). <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" /></blockquote>
