Now that I'm home and can look at the video full screen, I'm still not sure it's John's pump. He had the "power pump" which was smaller then the factory one but wasn't intended to go to the stock pickup line. Here's a pic:

Notice how it has a tall neck a that the top while the one in the video doesn't. The video also shows some sort of bolt like thing right above the hose clamp on the bottom. Even if it was John's pump, it wasn't installed properly. Interesting enough, I see the additional boot that was added to adjust for the size difference looks to be in great shape. It's the factory boot that's turned to gum.

I have his other fuel setup that uses the factory pump and boot but has a pickup screen directly fitted to the bottom of the pump and a different return line that sends the fuel straight down. The baffle is not a tuna can baffle either but something he made (Bill R was the one that used an actual tuna can). I put it in over 12 years ago and it's been running fine ever since. With that setup, there was nothing to really break down (the adapter between the pump and pickup screen was a friction fit piece made out of solid plastic).
