It's the fuel return pipe.

Cheers lads was running it today and no fuel was being feed back
into tank , noticed the pipe was broken, clear crack of about 3mm
wide in joining fuel pipe not plastic, is this normal ???
Did about 80 miles without a drop of fuel coming through

Ehm it all went in yer engine

The pressure regulator should open and let fuel back thru to the tank

Low fuel pressure or a jammed closed regulator would be the only things I can think of that stop the fuel return

Is she hard on fuel Joe?

Hoe to meet up with ya on saturday

Yeah Jay getting about 8miles to a litre at moment

only us paddy's would give a mileage like that LOL half imperial and half metric

8 miles to the litre = 36.32 miles per 4.543 litre or gallon

or 12.9 km to the litre

Yeah Joe I'd think you should be seeing mid 40's anyway

When is the last time you replaced the fuel filter? Any water getting into tank when you fill up? Cos a wet fuel filter will restrict flow severely
