HELP- wits end with XF vapour lock???
My girlfriends 1987 XF with a carbie (std issue weber) refuses to start about one time in ten and once or so each day just stops.
It will start again only if fuel is poured down the carbie but she is going nuts.
I have taken the fuel line off the carbie (but not as it is happening) and there seems to be lots of pressure as it gushes everywhere when the engine is turned over. There is no filter as such but the little gauze basket where the line meets the carbie is clean. Should I replace the pump or is something else causing a vapour lock or something??????
