I did this yesterday and this video was a HUGE help. Thanks! ^.^

Great video and I just did this with a new/used RX-7 that I bought a couple of months ago. However, I was able to adapt the stock fuel pump feed tube to my aftermarket Walbro by simply removing the white plastic clip on the stock fuel pump and then slightly trim it to fit down on the outlet of my aftermarket pump. This allowed me to use the stock feed tubes without cutting the tubing. As well it allowed me to use all the stock bracketry without running the hose clamp around the pump. I'll have a video of my update in a few months so hopefully people could do it that way as well. good vid though.

Careful with the gauge float.. i had to fish mine out of tank when it fell off and in tank. Was not fun 🤣
