The bypass valve in an oil filter allows the oil to bypass the filter if the filter becomes clogged. Some filters also have an anti-drain back valve when the filter is mounted in such a way as the oil could drain out of the filter. This valve prevents the oil from running back into the engine out of the filter which would cause the engine to be started with an empty filter every time.

Fuel filter is located under the car, under the passenger side door. Depressurize the fuel system first using the relief valve on the fuel injectors; it has a screw on cap and works like a tire valve. Catch the gas in a rag. The fuel lines unsnap from the filter when you press in the tabs and pull. Keep your face away, or you'll get a face full of gas like I did.

2004 Toyota Echo has gas starter works but engine doesn't engage I checked fuses and relays what should I do?
Could be the fuel filter or fuel pump. An engine needs 4 things to run, fuel, air, compression, and spark. Your problem could be related to any of these. Its pretty easy to check your air filter. Hard to check the fuel filter or fuel injectors. Compression is probably not the issue, spark plugs are easy to change but probably not your issue either. Start with checking/replacing air filter, clean the mass airflow sensor at the same time (its attached to the air filter box) with electronics cleaner spray, and then clean your throtle body (you don't have to remove it, just detach the hose and clean as you work the open/close valve by hand. If none of that helps, you want to check the fuel pump.
