You want to go for a 1:1 ratio FPR...
However it's unlikely that your current FPR is Weak as it's only a return line actuator, and limits the flow back to the tank therfore holding pressure at the injectors, created by the fuel pump. I would say to look at replacing your Fuel Pump (Walbro for example) if it's not already been changed, as this is the source of the Fuel Pressure... not the FPR!! |
