The Fuelab 515 adjustable fuel pressure regulator for TBI systems uses a large-seat design and adjusts from 10-25 psi. It provides two -6AN inlet fittings and one -6AN return to match common fuel line sizes. Intended as a universal solution, the regulator makes it easier to control mid-range pressure in throttle-body injection setups and to fine-tune system behavior for different pumps and injectors.
