Shop wireing Question

[oldandtired]

I do not have an answer for your question but I am wondering if you could rig something simple like putting a handle on the lid and using a simple ratchet strap or similar to open the lid or rig a handle to gain leverage.

Depending on the current draw requirements of the 12Volt pump, you could run it directly from an automotive battery charger, or just buy a 12 volt auto battery and run it directly from the battery and just recharge the battery when it gets low.
