Why does the Yili Cannon not get fuel after replacing the filter element?

The Yili Cannon does not get fuel after replacing the filter element because the air in the fuel system has not been completely purged, leading to insufficient fuel supply. The quality issue of the fuel filter element causes high filtration resistance, and the related sensor plug is not installed, triggering failure protection and limiting engine power. Reasons for the Yili Cannon's fuel level not being full: There is a leak in the fuel tank pipeline connection before the cannon, allowing air to enter. When the engine is running, this section of the pipeline is under negative pressure, and when the engine is stopped, fuel will leak out. Method to drain water from the Yili Cannon: First, disconnect the oil-water filter element's outlet pipe from the engine's suction pipe. Otherwise, water may flow back into the engine during drainage. Use your hand to close the oil-water filter element's cover to prevent fuel from spilling out. Then, use a wrench to open the oil-water filter element's exhaust port to allow water to flow out. Finally, open the oil-water filter element's blue drain valve.
I've encountered this situation many times. It's quite common for the fuel not to flow after replacing the filter, often caused by improper installation. For example, if it's installed backwards with the filter arrow not aligned with the intake port, fuel can't pass through. Or if the seal isn't tightened properly, air leakage introduces air into the system, resulting in insufficient pressure. I made this mistake too when I first started working on cars. Later I learned to first check the tightness by hand at the installation point, then use a test light to verify current flow. I recommend you reinstall it, making sure it's properly tightened. If that doesn't work, check the fuel pump - it might be clogged with debris from the old filter. Changing the filter is good, but poor attention to detail can backfire. Leaving it unresolved long-term could potentially damage the engine, so it's better to have a repair shop handle it early for peace of mind. Driving safety comes first - don't take risks by forcing it yourself.
