AFPR releases pressure after shut down?

[Redwidow]

How exactly does this fuel damper work? Is it like a simple restrictor? Is it adjustable? Ran off Vacuum? More info please

it has IN and OUT only and as I imagine it just shuts the channel when there's no any pressure...

my aem does the same thing. Also takes about 5 seconds to crank unless I leave the key on the on position and let dsmlink run the pump.

...when DSMlink's fuel pump "on" feature comes into play. You can have the fuel pumps prime with the key at "on" and not just when it's cranking...

interesting if EVO ECU has same function/option?

Not sure if your issue is like this or not, but I know the Aeromotive piece has issues from the factory with incorrect machining. There is a write up on it showing the issue. This can cause pressure issues at high boost and when shut down.
