Cold starting issues

[MettyMatty]

Whoops! - I tried to reply from my mobile but it obviously didn't like it.

The other night I fitted the 2nd replacement filter housing, primed it and it seemed to hold pressure a bit better.  I also cracked the banjos on the pump to witness fuel getting through.  Cranked it and it wouldn't start.  I abandoned it at this point as it was dark.

I've just gone out to have a proper go at diagnosing the fault as its actually not raining and in daylight and guess what? - There's bloody fuel weeping from the primer button.  3 in a row - Do I win a prize?

Can someone tell me with 100% confidence that no fuel should come out of the primer button at any time? - I can't believe I've got 3 with the same fault.

I'm not convinced this is my only issue but I really need to rule this out please?

Thanks.
