wondering if the spring has that much to do with actual pressure?
I would think those button valves do more for pressure?
I have put several replacement covers on ( chrome or correct AC ) with no  
known change in pressure
I have a test gauge made by putting a tee with small fuel pressure  gauge 
on a left fuel line.
