I would recommend replacing the entire tank unless you know that it has been done in the last several years. The tank will wear out eventually. Why not do it now. There are lots of complaints about aftermarket tanks. Many of them are flawed right out of the box. Best to go with Porsche brand even though it costs (much) more.

The easiest way to replace the tank:

Many thanks for the links... fingers crossed that this is the source of the problem vs. a red herring.

Any other reasons why I shouldn’t have any pressure (ie cannot even pump it up to 2-3 lbs)?
