Fuel filter and cap replaced a couple of days ago. Fuel started to bubble out round filter cap. It did it again this morning when I had to use primer bulb to start car. After that there was no sign of any leakage under car and filter housing/ cap clean and dry. At the end of my tether now and my mechanic is pulling out the remainder of his hair! Thank you so much for helping.

Then you have a leak and it is not sealed , drawing air .
