3320 fuel bleed screws

Hey,

I'm new to diesels so bare with me. I recently fired up my 3320 after sitting for most of the winter. It primed and fired up fine but stalled after 3 mins or so. Each re-prime and start up produced the same result. I figure there must be crud in the fuel filter/ fuel system? or possibly a bad pump...
Question is how do I prime the fuel system after swapping the filter? Where are the bleed screws located?

Thanks.

I bleed them by not fully tightening the filter bolts... by the way does the 3320 have spin-on filters, or still canister types like its predecessor ?

Between two filters is the official bleed screw, but i hardly use it.

It has a single canister filter. It's an early model 3320.
