question Zetor 7211 needs bleeding before it will start

Hi men/woman
I have a 7211 and when it stands for a couple of days I need to prime the diesel then tow it to start
When its going it starts and runs great
Few days later same thing
I have replace the hand primer a couple of years back no difference
There is no diesel leaking around the pipes /pumps/injectors In fact its very dry
Would there be an internal valve or something that needs replacing
Thanks in advance

What's happening there is when you leave the tractor without starting it for a couple of days is the diesel is draining back into the tank and you have to pump the hand primer to bring the diesel back up.


On a separate note, I don't think you should start your question with "Hi Men", as there are women using this forum too. You better thinking of us as Zetor enthusiasts.

My apologises to all the woman
fixed that now
