If you engine runs fine, you don't have a problem with air in the lines. If you do have air in the fuel line, the engine won't start until the air is bled out. Since your engine does start, runs, and keeps running, bleeding won't do anything.
It is possible that you don't have a good seal somewhere in the fuel lines, and when the engine is shut down, air gets in. Take a look at the things you touched, make sure you got all the gaskets installed properly. When the engine is running, look for fuel leaks, that is one way to know if a gasket is bad.
Lastly, the pressure gauge is most likely a vacuum gauge. As the fuel filter gets dirty, it requires more and more suction to draw fuel through it. This will be shown on the vacuum gauge and will let you know that it's time to change the fuel filter.
One final point, there are many many boaters who would LOVE to have their engine start in 5-7 seconds. On my boat, when it's cold (below 60), I need to energize the glow plugs for 30 - 60 seconds, then crank the engine for at least 10 seconds before it runs. So maybe, as another poster mentioned, it's just too cold.
