..and regulator

which one typically fails...

or do most replace both on the primary and secondary..

have no interest in pluggin em up..

 

the pulsation dampener is on the primary rail and the press regulator is on the secondary. the dampeners tend to leak and have a nasty habit of starting fires. the regulato will leak internaly most of the time. fuel will be in the vac line going to it.

 

thanks for the clarification..
