If the JDM version has the same fuel delivery system as the US version (GM Delphi) then you should be able to get a new FPR from most any GM dealership.
The US part # is... 8-17114-728-0
i believe it does well looks the same.
over here our Holden deal with Isuzu and Gm stuff so thats where i went through and they came back with the 326$ price for the Fpr
