I fixed my Onan

For those who have ever fixed anything knows, the first thought is that more is wrong than really is.  So when my Onan Genset ran out of gas I thought fuel pump or carb.  So I bought a new see thru filter to start but when I went to change it the fuel line was loose.  It didn't seal up good so air was sucked in not the gas.  So some gas line and a new filter and all was good.
