How to take the air from the injection diesel pump? I m from Brazil, my Suburban is diesel V8. I think the problem is air inside the diesel sistem... after empty diesel tank...

Well to take out the air lock in the system,first of all you must look for the fuel filter ,just beside the fuel filter ,you will find another filter which is the pre fuel filter which is the water trap,on the pre fuel filter on it's top there is a feed pump for the diesel ,now what you must do is to see for the diesel hoses ,follow it ,you will find inlet and outlet for the hoses,you must take out the hose that goes to the outlet.By then start to press the feed pump,the pressing is done by your palm,keep pumping until you see diesel coming out where you have taken out the hose until with a good flow,now put back the hose,then press the pump until it become hard to press to press.Now start the engine,hope that clear your mind and solve it

Crack open 2 lines as a time aand crank the engine 4-5 revolutions till fuels dribbles from them the retighten and do 2 more till all are bled than start it
