I know there are a lot of threads on here concerning this issue, bucking, stalling, etc... I've read quite a few of them but nothing I've come across has helped with what I'm dealing with. My 85 FJ60 was running great around town. I put in the ac delco charcoal canister and rebuilt the carb. I've confirmed the Idle solenoid is working. The other day I took it on the freeway for the first time and couldn't get past 50 MPH and it started feeling like I was running out of gas. I pulled off the freeway and even at lower speeds it was feeling like I was running out of gas, but I had recently fueled up, so I knew that wasn't the case. I got it home and was looking at things and noticed that while running the fuel filter is collapsing (photo below). When I rev it up to 2500 RPMs I can see the float bowl level drop below the sight glass and when I let off the throttle, it seems to take longer than it should to get back up to the middle of the sight glass. I disconnected the charcoal canister, opened the gas cap and still collapses. I don't want to start swapping hoses around or dropping the tank before asking here for some advice. I just don't know what would be causing this issue, but I believe it's a fuel delivery issue causing my 60 not to run properly. I also installed a brand new fuel tank and pick up tube.
Any help is welcomed and appreciated. I've been a 40 guy for 30+ years, this is my first 60 and first time having to deal with all the extra smog stuff. I'm trying to learn. Thank you in advance for any help offered.
PS: I know it's a cheap and not the correct fuel filter and I have the correct one. I swapped it out to see if the other filter was clogged.
