Frequently the engine is tuned to work for the typical tension specification of your fuel pump. Consequently obtaining an OE-proposed fuel pump is usually a clever solution.
After this process, fuel introduces into the pump by a suction valve and filter mesh socks (which helps prevent dust and rust from entering into the pump).
