My air compressor will only build pressure up to 40 psi
my compressor runs fine no leaks any where, but stops building pressure at 40 psi. the motor does not bog down it runs fine, just wont build pressure over 40 psi.

I think if you read the pages and comments here that will help you understand the underlying reasons why an air compressor acts like yours does.
