Is the black hose on the input to the electric pump new or is it the original---this is the hose that has caused drama to my WG . It can look fine but can have a tiny crack or pin hole and since its still on the suck side of the fuel system there will be no visible fuel leak, it just leaks a bit of air in on a random basis.
There is also the possiblity of air leak in the flexible hose at the tank, but none else seems to have had problems with this one..good luck, hope its just the hose.
