Standard Motor Products PR318 Fuel Pressure Regulator - High Performance Replacement Part for Cars, Trucks & SUVs - Ideal for Engine Maintenance & Repair

The regulator came well packet with the clamp, o-rings and gaskets so that it fixed the gas leak of my Jeep Wrangler TJ 2002 4.0L because of an broken old rubber o-ring, BUT the pressure regulator does not hold the pressure - which is the main purpose of it.After replacing my old regulator my Jeep now needs 2-4 cranks till it starts up, which means I have to replace it again. I went with this more expensive pressure regulator to avoid exactly that issue, but ran into the same problem as one of the other reviewers. I'll try a Delphi next instead, which is even more expensive, and hope for the best.
