Thanks for all the great information!
I took a quick look at my fuel strainer a couple weeks ago but it was a quick look as I didn't have the tank as empty as I thought I did. I'll check it again.
The fuel cap trick doesn't work on my car as it doesn't run at all yet.
The bubbles are coming out of the fuel pump on the inboard side, next to the engine through the clear tube that goes back to the filter. My camera is dead or I'd show you a picture.
