Fuel Damper ?

[Shannen Durphey]

Corvettes with TPI have a damper in the form of an "empty" fuel
filter.  The LT1 equipped Vettes have a smaller diaphragm type damper
just above the rh valve cover.  The damper that I mentioned having
troubles with is actually called a pulsator, and is mounted inside the
tank between the pump ant outlet line.
