My BBK fuel pressure regulator went bad. It's leaking fuel and sucking fuel into the vacuum hose. The car sat for over 10 years so I'm assuming the diaphragm dry rotted. I see a kit on BBK but it says it's for 2010 models and newer. Mine if from 2008. The only difference I see is the vacuum port which is on top on the newer models but on the side for mine. I emailed them and they said it's the only rebuild kit they sell and I have 30 days to return if it doesn't work. Has anyone replaced the diaphragm on their regulator and know if this kit will work on older models?
