Making a larger Bijur Pump Tank

Running lights out, trying to make things last as long as possible and I hate running back to fill up the lube tank especially with a dumb funnel into a small container that wasn't built right. I wanted to create a custom plexiglass box which just sticks out a bit to allow for a better entry port. I think as long as the fluid depth height doesn't change it shouldn't mess with the gravity head load for the bijur pump. At that point I might be tempted to have a secondary float valve pump to autofill it from a larger way oil container being gravity fed from a 5 gallon bucket for example.

I worked in a place that had a huge Mitsui HMC. 1000mm pallets, enormous box ways, 40 hp spindle, etc. It had the smallest Bijur lube tank I had ever seen on a CNC. The lube tank on my Mori SL-3H lathe is larger. The tank itself rusted through (!!), so the maintenance guy "fabricated" a wider tank that was the same depth and that extended the fill intervals by a lot.

Pop bottle upside down, tube extension into tank.
When level goes down, air will go in tube, allow oil out to fill tank until blocked again.

I found a pump w hose on mcmaster that fits in the top of the 5gal bucket. Grab a dolly for the 5 gal bucket too, it was cheaper off ebay. Cut the hose to fit easy on the tallest tank we have and it made topping up a 5min job. Took all the funnel etc trouble out of it.

This set-up is on one of my large lathes.
IDK if it was OEM or what?

Hopefully there were no long term problems from the creative maintenance guy, in principle I think as long as the depth doesn't change should be a good solution. I'm ordering plexiglass and weld-on as we speak hehe
