Review on BD Diesel 1050071 Common Rail by Tarus Clinton

Reliable product. Replaces the relief valve that costs $600 but is defective. Unless you plan to use a 1000+ horsepower fuel rail, this shouldn't be a problem. The plug itself is 5/5 easy to install, but you should have enough mechanical skill to get at it as it is located behind/under the EGR and intake manifold. This is not a 5 minute install/replacement for those who don't know how to operate the motor. You certainly don't need to be a certified mechanic, but be aware that you will need to remove the intake manifold that the EGR is bolted to, so make sure you have spare gaskets in case you damage the factory ones.
