98Sc2 Fuel tank buzzing sound not pump
I noticed a VERY loud intermittent and somewhat short lived buzzing sound coming from the fuel tank. I replaced the pump even though pressure was good. Started the car but buzzing returned. There is a metal cap with a hose coming out of it, just across from the pump (vent hose?). It seems to come from around there or the charcoal canister. This summer was the first time I noticed it. It seemed to coincided with p0172 but I rarely heard until this winter. Could it be related to a bad purge solenoid?

The purge solenoid is on the back of the engine. Do you mean the vent valve or something?
I’m getting an intermittent buzzing from the exhaust system. The strap of the pumpkin muffler rusted through and the system is now held in place with a gear clamp around the exhaust tip of the pumpkin muffler.

When I first started looking for it, I felt a vibration coming off the fuel lines back from the fuel filter. very strange.
I read that if the purge solenoid fails, the system vents it off into the atmosphere? Is the buzzing meant to act like a whistle on a tea kettle, or squealer on brakes? It doesn't sound like a loose piece of tin? I hear it stopped and rolling
