this is a major common problem on a zd30 diesel engine and in many other diesel engines.the bolt shown on the video controls the amounts of fuel return .

One info if your car start hard over night: That bosch overflow valve it have a blender for air bubbles bulit in, (that small hol) and it won't keep the pressure into the fuel pump (the fuel pump don't need pressure to work, the fuel pump need fuel inside to work, not AIR . Don't confuse the fuel pump with the injection pump. The fuel pump it's inside the injection pump in this Bosch vp 44. The retun hose are conected directly to the fuel pump by that overflow valve. So if you have any leaking on the return hoses , that leaking will fill with air your fuel pump , throug that small hole (the blender). Check any leakage by filling the return hoses with compress air. (And of course check the one way valve on the fuel filter olso with compres air ). You can check all the injections likege at once assuming that the one way valve is working properly: take out the fuel hose from your fuel tank , (turn and return) fill with compressed air the turn hose , and block the return hose. If you have broken hose you should heare or see it. (The metal pipes can't be checked this way because of the pressure valve from injection) . Again don't confuse the fuel pump with injection pump.

i think you also know the engine runs perfect evwn with the fuel return hose is disconnected, right? meanin even uf there is a leak on the return hose it would'nt hinder the operation of the pump to make the engine run fine

@@endurofan9854 try to disconnect the return hose and after 24 hours idle start the engine . It will start very hard because, your fuel pulp will be empty at this specific pump "vp44". Any engine will run with the return hose disconnected, and in some cases the return hose goes through the fuel pump, and in this specific case "vp44" if you have a leak on return, your car will start hard after 24 hours idle.

As for as im aware the only failure point on a banjo bolt can be fit up, as in the mating surfaces. If there not clean or you've dropped it its probably scratched. That's also why NEW crush washes are essential. I'd say you'll still have problems with it tomorrow when it leaks down overnight. The problems more than likely in the delivery lines

there a little valve in there, a blast bearing and spring. If it doesn't close, I think it can't build pressure in the pump.

Stop being deceitful to pple, if its that buncho bolt how does it affect the car by not cranking. From the first that car shuld have cranked bt wont start, how does a bolt stop the starter from cranking.. wen yo video started yu said the car wont start, did t affect cranking. That bolt has no impact on zd30 injector pump.

Very Fake 1st - You did not run the key to crank the engine, just went to key on not starting. 2nd - The Bolt you removed is the same one you Boltted again. ( the one you show as old is newer than the one you removed. 3rd - The bolt holes are supposed to admit the air yes cause are the same holes that feed the diesel to the injection pump.
