Help with stock EFI

More pics is going to be hard because I don’t have any. And the tank is sitting under a workbench at my shop covered in dust. But I bought a new tank, cut a big hole in the top, welded studs (3) to the top, and modified the spring loaded telescopic base for the depth I needed. I used a new tank because I knew I was welding to it and cutting on it and I wanted one that never had gas in it. Plus my tank was original to the car and had rust in it. If you weld to an old one, fill it with water and-or purge it with an inert gas. I used this setup with zero problems for a while stock and now it’s completely different for the turbo setup, needed a lot more pump.
Can you describe what you had to do to the telescopic part to make it work?
