Full Version: Fuel Pressure Regulator
can anyone tell me if i can install an after market fuel pressure regulator without messing with the one in the tank.
no, as there is no fuel return line
Hi,
Since I'm looking at the same problem I allready did some research.
I preferred not to to go HKS, Apexi or Greddy with extensive mapping an bigger injectors (expensive and imho. to much hassle for a rather small problem).
At the moment my motor light sometimes comes up while accellerating and the car doesn't run perfect with airco on.
Found a few options:
Change the petrol damper for an an old fashioned hollow toyota petrol filter plug (MR2 sw20) for more flow and alter the pressure regulator in the petrol pump slightly (pressure gets higher and the problem will be solved but the downside is that it will stay this way so the mixture gets too ritch while not accellerating....)
At the moment I'm talking with FSE and waiting for an answer. this firm delivers perfect fpr's (for approx 50 pounds) that can be adjusted and work on motor vacuum but only on the rails and not for systems with the regulator ond the fuell pump (as mentioned above, ther is no fuell return line on the IS).
See what they will come up with.
