Default Fuel Tank Air Bubbles

Was tuning my engine for this Sundays big race replaced all the fuel hoses with clear as I was tuning noticed small bubbles passsing through the fuelline into the Carb.

Pulled my tank submerged into water holding hoses plugged one hose and blew no bubbles in the water.

Having bubbles in the fuel line when motor is running is that normal???

Clunker wasnt exposed to air tank was full

i have never noticed it in mine, you could try putting a longer pressure line on about a inch longer than fuel line

Are you running a fuel filter?
If yes, the filter might be the cause of the bubbles..
Remove it and you shld be good to go!
(do it at your own risk though.. then again nobody uses them anymore right?)
