Help with stock EFI

Ok @Truckie sorry it took a few days. Here are some pics of my modified sending unit. I did this in about 2012 so i really didn’t remember much about doing it and this has jogged my memory. It’s pretty clear that I cut and shortened the top portion of the outer “sleeve” to the depth of the stock tank and the “inner” sleeve is just a slight press fit in to it. The bottom of the sending unit lightly bottoms on the tank floor (that’s how it’s designed to sit) and once bolted in at the top has no way of coming apart. Hopefully that will make sense once you see the pictures. I bought this new from NAPA so I added their inventory pics for reference.

Thanks that definitely helps. I pulled the pump out of the donor so I will modify it first so if I screw up I’m not out any money.
Did you make any kind of ring to go inside the tank for the bolts to pass through to make the hole in the tank more rigid?
