If you main tank is pressurising then you have a venting problem that needs to be rectified.

Hmm. I’ll have a look, but the breather valve thingy on the TD5 is pretty small and it’s ok during normal use, so perhaps it’s to do with the volume of air needing to be moved. (Ie, the engine uses a litre of fuel every 4 or 5 minutes whereas the pump runs at 8-10L per minute. That’s 40-50 times more air!)
