Ticking coming from the fuel tank

[Bozmeister]

I have noticed I have developed a loud ticking sound coming from near my fuel tank when I switch the engine off, the had started after I had changed my Carbon Canister. It ticks fast then gradually slows down to a stop, any ideas? Thanks

fuel pump related issue?

Fuel flow seems to be as good as it normally is/has been, MPG has also averaged the same too. Diagnostics seem to state the SFT and LFT are all good. It started instantly after changing the canister.

If its the ticking I'm thinking of... It has happened in all my cars and others... It's nothing?
