Need to control fuel pressure but dont' want to plumb in an external regulator? Now you don't have to if you have a factory equipped EFI VW or Audi. This Eurospec Regulator is adjustable from approx. 3.3-5+BAR, and mounts in existing factory regulator provisions in the stock rail, vacuum referenced 1:1 like the factory regulator.
May also fit other factory applications.
Note:This regulator has a groove machined in the body to allow the use of the OEM regulator clip, be aware of others on the market that do not, and thus cannot use the stock clip. These regulators do not come "Pre-Set," and will need to be set to the desired pressure by the installer.
