The mechanical fuel pump on my GQ is leaking engine oil so I bought a new one to replace it with.

It came with a new gasket as well but the gasket feels kinda hard so do I need to put some silicone around it? Also, does the gasket only go one way? It looks like it can go either way but it came with a disclaimer that said warranty is void if gasket is not fitted properly so I'm just a bit cautious.

Any advice appreciated.
