The fuel pipe from which runs from the metal fuel pipe to the fuel filter was allowing air in

I replaced this with a piece of fuel hose and a none return valve and I now have no air and a much better starting car
Strange thing is mine always starts 2nd time then stops after about 3 seconds. This goes on until eventually it continues to run and I’m good.
Maybe I have a combination of air in the fuel and some electrical gremlins.
