Wolverine STORM On-Tank Internals Assembly — Standard or High Pressure

Plenty of legacy STORM on-tank regulators are still in service, and when one starts creeping or will not hold a set pressure the fault is almost always inside rather than at the fittings. The internals assembly is what you replace instead of writing off the regulator.

Wolverine built it in two pressure versions. Standard covers normal engine pressures; the high pressure version exists for setups that need output above that band. They are not interchangeable on a whim — fitting the wrong one gives you a regulator that works but will not reach, or will not come down to, the pressure you are aiming for.

This is a rebuild part for a regulator generation Wolverine no longer build. If yours is the current STORM Category 5 regulator, its parts are different and the Category 5 regulator base is the piece you want.

Specifications

Good to know before you buy

Know which pressure version you are running before you order. The two look similar in a parcel and the difference only shows up when you try to set output.

Fit fresh seals while it is open. Our O-Ring Service Kits range carries a STORM Regulator option, and an internals swap is the natural moment to use it.

Frequently asked questions

Which version do I need?
Standard for normal engine pressures, High Pressure for setups needing output above that band. Tell us your target pressure and we will confirm.

Will this suit a Category 5?
No. The Cat 5 is a different regulator generation with its own parts, and the base is listed separately for it.

Is the regulator body included?
No, the internals only. This rebuilds a regulator you already own rather than replacing it.

Is it worth rebuilding a legacy regulator?
Often yes, because the body and the tank thread are the expensive parts and they rarely fail. If the body is damaged, that is a different conversation.
