Roberto: the usual mode of failure of the Bijur system is the vacuum diaphragm on the pump. These have been NLA for decades but there are folks who repair them. It's easy enough to check - just apply some vacuum with your mouth or a small vacuum pump and see the the diaphragm holds vacuum. If it does you can loosen the vacuum line to the pump and with the engine running, repetitively apply and release the vacuum until oil is seen emerging from the oil outlet fitting. There is also a manual priming method, you might want to read the Bijur manual available on this site. In addition to the felt filters in each drip plug there is one in the pump intake at the bottom of the jar - you might want to make sure it's clean. For Bijur oil you can use SAE50 motor oil or SAE 90 GL-1 gear oil.
One thing you might consider while the pump is out for repair is to remove the outlet oil line from the pump and attach a hand pressure oiler like the one pictured. If the lines are intact and the drip plugs are not clogged you'll eventually fill the lines and lubricate all the fittings. You can continue to do this regularly until the pump is repaired.
Apologies to Tom for going so far afield on his post.
