I have a TB42 on dual fuel. Runs great but I don't like the always 'on' mechanical fuel pump - every so often I smell petrol. So bought a terrific electric pump only to be used when on petrol once every two - three weeks.

Just have one doubt: leaving the mechanical fuel pump in and run dry for ever does not sound OK to me .
-- Can I fill it with oil and connect inlet to outlet and let the pump circulate ? Or would that eventually cook the oil and go booom ?
-- Or can I safely remove the mechanical pump and forget about it?

Thanks !!
