Thanks for asking your question. I will try and help you out.
Unfortunately when dry filters are installed. The fuel system can get a large amount of air in the system.
I would try refilling the filters and starting the engine.
Some engines have a hand primer on them. If yours does, it will be on the engine and can be operated to remove the air.Please reply back if you need more help or have more questions. I am happy to assist.
