I have a Perrin fuel rail with a stock FPR in place, if I disconnect the fuel line and vacuum hose and reconnect them to my aftermarket FPR would the stock FPR let fuel out our will it stay closed with no vacuum line hooked up.
I have the fitting that will let me install the FRP on the side of the Perrin fuel rail with braided line, can't find anyone local with a blocking plate. They want to tap the fuel rail, I don't want to do that.
