sorry, the tank!
I got confused , with the stress i guess!
i had no tank issue ... the prime bulb i installed was of no use.... i succeeded to have diesel coming from pumping it with my mouth...
this is so strange...the engine running so good, shut off normally, and then no diesel coming...my only hope is a clogged filter
now I put it a new one, and i have to engage the great combat of the ve pump priming
