UPDATE: I have spoken with several LPG conversion places that have all said the same ting the sub-tank pump is not changed. So I have replaced the fuel pump, the in-tank sub-tank and then noticed that was not working ... I retested the new fuel pump from the battery test I used yesterday and no power. I then tried it via a different battery and both work, must have been a faulty battery. I am however still having not getting fuel.
