Properly adapt a factory fuel pressure regulator to your high-flow fuel rail with the confidence that it will not leak. This adapter features a trio of 6AN o-ring boss ports. A Fuel Rail Fittings Kit is available separately. This adapter allows for feed and return to be on the same side or on either end.
A third port is also set up for a 1/8" NPT fuel pressure gauge (making an inline gauge adapter unnecessary).
Fuel Rail Fittings Kit is not included in this base kit. Add it to your shopping list. :)
