I needed to address drilling the holes for my fuel tank sending unit. I used the gasket for a template and drilled them out. After that, I filed any burrs and got to work with the inside of the tank. I used about 12 brand new shop rags, brake clean, and a magnet, but it cleaned up really nicely. I kept using the new rags to monitor how dirty they were when I was done wiping the tank. Once I saw satisfied, I re-installed my adapter ring for good with my Viton seal. (bought a 9" remnant from ebay and made my own gasket) The fuel sending unit is a universal sending unit that can be had on eBay or Amazon that reads 0-90 Ohm.
Once the fuel sending unit was in for good, I had to bend the level sender float so that it would read empty and full while still clearing the recess panel. It took me a little bit to figure out the angles, but it turned out pretty good and I am satisfied that it will read correctly. Having a 5" hole in the top of the tank helps with making those small adjustments too.
All buttoned up and installed for a final time.
Now was the part that I was excited to start; modifying the stock fuel pump assembly to run at constant 58psi. I kit is from Carl at Vaporworx, and I have been patiently waiting for the tank to be done before I did anything with the pump. I used a little cleaner and a scrub brush to clean up the pump assembly and it looks brand new!
I followed along with the highly detailed instructions that were provided, and it was incredibly easy. First step was to remove the retaining ring and remove the stock fuel pressure reg.
Once it is removed you end up with this. There is also the grounding ring that needs to be temporarily moved to the side.
This is the heart of the conversion. This is an adapter that was developed by Vaporworx and is what allows for the new fuel pressure regulator to work properly.
Like it mentioned in the instructions, the filter was in the way for the adapter to seat properly, so I had to gently move it to the side. I ended up installing it at an angle, and it worked like a charm. Hard to get a picture, but there is the filter in the way.

Here is a comparison of the 4th gen fuel reg vs. the stock one that came out. 4th gen on the left and stock on the right.
And fully installed. Don't forget to re-install the grounding ring.
Fully completed swap. Here are all of the tools that were required for the job too.

And here is the fully installed tank. I threw some paint on the stock retaining ring, but will get a new one before final install in the car. For now it works fine to hold it down to keep debris out.
Ready to go into the car! The only modification I may make is to bend up a hard line from the pump assembly to the driver's side front of the tank for a cleaner install.
For those wondering how I did from a cost perspective, I am listing it below:
LS3 Camaro fuel Pump $59.00
Colorado Mount w/ Ring $2.00
Recessed Tank Panel Metal $30.00 (even though I already had it)
Parts from VaporWorx $101.99
0-90 OHM Sending Unit $5.00
Viton Gasket $8.96
That is a grand total of $206.95
Still need to wait to see how it performs, but I have no doubts that it will live up to my expectations. I feel that is a much more reliable option than the Spectra tank, despite the work to complete.
