I was getting tired of waiting for the Livewell XL so I decided to follow some of the DIY livewells out on this forum and on youtube. I bought the 40 Lb "Vittle vault" at my local pet shop on sale for $28 Canadian dollars http://www.petsmart.ca/supplies-training/storage-scoops/vittle-vault-stackable-pet-food-container-zid36-6700/cat-36-catid-100071?var_id=36-6700&_t=pfm%3Dsearch. A Tsunami pump for $24 and a fuel priming bulb at for $9 at Canadian Tire http://www.canadiantire.ca/en/pdp/marine-aerator-500-gph-0793513p.html, http://www.canadiantire.ca/en/pdp/i-d-primer-bulb-3-8-in-0799018p.html#.VRtMRWd0ycw. I learned how to make two cheap check valves from Youtube.https://www.youtube.com/watch?v=DG6own141z0. The only thing I didn't really like about the build was that stupid lid. I found a Kayak hatch that almost fit at Aliexpress.com $12 US Dollars http://www.aliexpress.com/item/8-kayak-hatch-kit-with-red-bag-Round-Kayak-Hatch-Cover-Kayak-Accessories-fishing-kayak-siut/32273981132.html. When I got it I tried a couple of different fits and settled for this.
Remove the lid and set aside.
Gently pry the press fit threaded lip from the container and set it aside.
I used the hatch seal as a template on the threaded lid to mark the holes on the top of the lid. You need to be careful as the hole pattern is irregular to allow for the hinges
Cut out the inside rim of the lid making sure to stay away from the threads. You can smooth them down and file to fit the hatch quite easily but it's not necessary
Fit the hatch to the lid and check the hole placements and remark them (AGAIN %#!@*).
Apply marine goop to the inside of the threaded lip and snap it back into place. Note that I made a mark at the top center so I dont end up having to remark the hole for a third time.
Once the marine goop has set pop the seal and lid in place and screw it in place.
This took about half an hour and was totally worth it.
I'm about 70 dollars in and just about finished.
I will post the plumbing when I get the valves made.
