Hey guys, I'm new around here. I have a 54 3100 that I just started a build journal for if you guys wanna go check it out. But I'm here with carb questions. The old fuel system had some heavy rust in the tank and lines. Truck ran fine but while replacing the tank and lines, I'm also replacing the fuel pump and rebuilding the carb. What I'm looking for is a recommendation for a good complete carb rebuild kit. Also, as you can see the stock fuel filter setup is no longer here, so I'm wondering what I need to set it back up the correct way. Thanks!

Also does the return spring setup look correct on this?

When the truck wasn't running the gas pedal would stick down, I'm wondering if the return spring isn't correct or if I need a new one. I appreciate any and all help, thanks in advance!
