Any tricks for finding a leak in fuel line ?

Okay now I’m pretty confused , I temporarily replaced the rubber connections with some clear plastic hose just to see where the bubbles are coming from and at first no bubbles came up so I thought I was good. I took it for a drive and it sounded a lot better when I gave it some gas , but after a bit longer than before it started bubbling and hesitating and guess what, the bubbles were coming from the tank so I siphoned most of the gas out and took the sending unit out to check the pickup line for any rust or damage but the thing is SHINY brand new … I think my tanks pretty big and I was wondering if there’s only like 5 gallons in the tank would it not fully submerge the pickup line resulting in that bubbling ?

I would think that if the tank is the original and you are using an original pick-up, this shouldn't happen as it would have been a problem since the car was new. If you can, take the sending unit back out and plug the input end of the pick up tube . Submerge the unit in a bucket of water and blow air through the output end of the tube . If there is a leak, you should see bubbles in the water.
I'm thinking it may be leaking where the tube going into the tank is soldered to the piece that holds the sending unit to the tank.
