The FPR allows you to fine-tune your fuel pressure to the exacting requirements of many of today's diesel trucks. With many drivers running highly modified injection pumps (or two) and high output injectors, a standard pre-set lift pump does not do the job. This regulator from FASS allows the driver to set the pressure out of their lift pump to what their requirements are from 0-100 PSI. As an added benefit, FASS has also engineered a boost compensation port. This will allow you to run an air line from your intake manifold so that as additional air pressure (boost) is seen, the regulator will deliver incrementally increased fuel pressure, very beneficial when under active acceleration and fuel demand as been increased.
