does anyone know a company that makes a fuel pressure regulator for the liberty. I would love to find out and get one if avaliable. on a tpi motor I have I installed one with a guage on the fuel rail and it helped give it an extra little kick, plus the fact that factory regulators are never exactly the same from one liberty or should I say 3.7 to the next one, they help to atomize the air/fuel ratio when going into the heads, and better atomization means a cleaner burn and uses the fuel more efficiently any help would be appreciated

I'm not sure but I think our pressure regulater is part of the fuel filter(could explain the $135 cost of the darn thing),the regulater was part of the filter in my '01 grand also.

do you know if it has any adjustment to it, even though if the stock one does the factory will not likely let you know that
