GQ TB42 replace mechanical fuel pump for electrical.
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?
Looking at the images for the mechanical pump, it is basically the same oil splash lube as my ol' Fairmont. I just made a metal plate that matched the hole to blank it off. But I hope someone who has done it can set you straight.
