Hey guys, just installed my AEM fpr to lower my pressure since the new walbro 450 put me at almost 80psi.
Got it put on had a small leak where the return line fitting goes. Found the nut wasn't very tight. So I snugged it up and no more leak. Started the car psi went back to around 45-48psi let it idle for ten minutes shut it off psi dropped to 28-30...normal right....anyway look about 10-15 minutes later my fuel pressure gauge reads 0! This normal with a aftermarket fpr? My OEM would hold atleast 20psi all the time.
I don't see any leaks.... just want to make sure this is normal if not what do I need to check.

Thanks

 

That's normal mine does the same.

 

Mine does the same as well. Mine drops pretty fast after turning the car off though.

 

Normal. Mine did that when I had that FPR.

 

Thanks
