Air often gets into the fuel line because of cleaning the filter or any maintenance. This causes the engine to have problems in starting and also air can cause corrosion of the filter element.
So in Marine fuel filter during changeover of filter or putting back the filter after cleaning, priming is done in order to remove air from the system.
The procedure after cleaning the filter and putting back.
1)put the filter after cleaning
2) open the purge cock and open the fuel oil suction valve. Now air will come out of the the purge line. Close the purge valve once only oil flows through the line.
3)now the filter is in operation.
