Accusump Question
The pressure relief valve on the Accusump on my C5 started weeping a few drops of oil recently. Since it is preset to open at 175 psi, I'm tempted to replace it with a plug, but the manufacturer's instructions warn against doing that. Since my engine isn't going to generate oil pressure anywhere 175 psi, why do I need the valve?
Thanks!

Somebody give me more explanation on this. I'm looking at installing an Accusump this winter and if the canister is good to 175 psi and the engine can't put out anywhere near that pressure - what good is a 175 psi pop off valve on an LS engine????

Just about all thin wall pressure vessels have relief valves to prevent explosion. In the case of the accusump the oil is separated from the air pressure by a piston with seals. The pressure relief valve is on the air side. It's a safety measure. Sure, you could plug it, but it would be best to replace the valve with a new one that works. They are inexpensive.

That's why the pressure relief valve is there. Trust me several people including myself have had the relief valve go off and it pukes oil everywhere. I always check my air pressure and maintain it at ~ 10 lbs.

If for some reason you were to lose air in the tank the oil will expand under heat and will have no buffer and as result, your tank will explode

7psi is the recommended pressure when empty. It assures all the contents gets pumped out when there is a loss of oil pressure. Too much air pressure (when empty) will not allow the accusump to fill properly.
You are not off in your thinking of the 175psi relief valve being high. It is highly unlikely the pressure or oil and/or air will ever get anywhere near that. I'd bet that is the maximum pressure the container can contain (when properly installed) before something gives. In addition, the piston that separates the oil from the air has seals to keep the oil out of the air. Some oil can get by, but the idea is that the two are separate.
I recently did an install and was provided with a used accusump so I completely rebuilt it. If there is ever a motor failure the accusump should be rebuilt to prevent any contaminants from the failed motor to get into the new motor. Same thing goes for anything in the oil system. Lines, oil pumps, etc. should be cleaned out/rebuilt or replaced after a failure. Oil cooler should be either replaced or sonic cleaned. The only oil cooler I know of that can be rebuild is the laminova. This is what a rebuilt accusump looks like before assembly:
