air on return fuel tube

I got a 320i 1985 ,sometimes starting it isn't easy.
When hot and with the gas tank full,when the pump starts I can hear a loud bubling inside the tank.
But i already put a small clear tube between the fuel filter and the injection ramp and can't see no air passing so I'm assuming it isn't coming from the pump.
Is this normal ?

Most likely it's the sound of return fuel from the regulator pouring back into the tank. However it's odd that you can hear it so loud.

When the engine is running ,and with a clear tube on the exit of the pressure valve regulator I can see very small bubbles coming from it.witch I can't understand why ,because like I said i do not see it coming from the pump. About the sound it's like if you blow on a tube inside a bucket,some times after the pump works and stop,if turn the key off and on I still have a little more bubbling.
Otherwise works ok.

Thank you.

Very unusual. Does your fuel return line get close to the exhaust?

No the fuel lines go near the driver side ,every thing is standared.
