Dear All - I have a mildly irritating problem with fuel syphoning out of the line and back into the tank.
It's only really noticable if I leave her standing for more than a week, which unfortunately is more often than not these days. The problem arises when I try to fire her up and can end up cranking her over until it flattens the battery.
It suggests to me that either there is a leak in the fuel line somewhere, although I can't find one, or the fuel pump is weak, however when she is running it's very smooth. BTW it's the original mechanical pump not the electric type.
I guess I could fit a non-return valve but this might just be papering over the cracks.
Any ideas? Thanks.
