Unclogging a fuel pump can vary depending on the type of pump you have, as well as the cause of the clog.
If you have an electric fuel pump, a clog can be caused by contaminants in the fuel or a damaged fuel filter. The first step to unclogging the pump is to identify the cause since each cause requires different methods of resolution.
To determine if you need to replace the fuel filter, remove the filter and shake it to see if it rattles. Often when a filter is clogged, the debris blocks the filter, limiting or stopping the flow of fuel.
If there’s no debris, you’ll need to check the fuel line and tank for contamination.
If the issue is a clogged fuel filter, the only resolution is to replace the filter with a new one. For fuel contaminations, the fuel tank and fuel line need to be emptied and cleaned. Contaminants cause a buildup within the fuel pump and the only way to remove the buildup is by disassembling the pump, removing the buildup and then reassembling.
If you have a mechanical fuel pump, the same steps apply but will involve removing the pump. Again, the first step is to determine the cause of the clog and then take the necessary steps to resolve it.
Overall, unclogging a fuel pump can be complex depending on the type and cause. It is important to investigate the root of the problem and take the necessary steps to eliminate the clog and ensure that the fuel system is working properly.
What are the symptoms of a clogged fuel pump?
The symptoms of a clogged fuel pump vary depending on the degree of the clog, but typically include a decreased engine performance, difficulty starting the car, sputtering and stalling, loss of power while accelerating, and rough idling.
