Splices into the wire feeding your stock fuel pump and raises its voltage (up to 22V instead of the stock 14.4V), so the factory pump moves more fuel without being replaced. It's plug-and-play, with an adjustable Hobbs switch to set when the boost kicks in.
why this one — JMS rates it to support up to 1,000 hp on a single stock pump (1,300 hp with the factory dual-pump setup), making it one of the cheapest ways to add fuel capacity before committing to a full pump swap.
