I have sourced the part of the engine that is leaking onto the ground having believed that it was an oil leak. It appears to be coming from the injector pump and the area directly below this pumps in wet at all times (leaking fuel).
I have scoured the internet parts sellers to try to find a "re-seal" kit for this pump but have not found anything. I am told that this is a Bosch part and, as such, needs to be purchased directly from Bosch or an authorized dealer but I don't think this is going to work having contacted several service groups in the area.
Does anyone have a clue as to how I might proceed to fix this problem without going to a dealership to have my face ripped off? Thanks.:surrender::
There is no commly sold kits for the Fuel Injection Pump because they seldom cause any issues and there is parts of the Fuel Injection Pump that if you move some parts around changes the calibration of the Fuel Injection Pump.
It was back in 1975-1980 but I used to work in a Fuel Injection Shop.
I could help more easily if you just said where the Fuel Injection Pump was leaking.
Also do you know if you have an MW or M type Fuel Injection pump.
The M Type takes a special Socket to remove the Delivery Valve Holders.
If it is an Oil Leak coming from the Bottom of the Fuel Injection Pump there is a Pan on the Bottom that is sealed with a fat Square Crossectioned O-ring. You can buy the O-ring as a seperate part from Mercedes or Bosch or simply remove the Pan and carefully Apply Silicon Sealant.
However, the Screws on mine were on really tight and are made for a Blade Screwdriver. That makes the job hard to do with the Fuel Injection Pump on the Engine.
The Throttle Shaft O-rings can be replaced; another leak area.
Where the Fuel Injection pump bolts to the Block has a thin paper Gasket. That would not come in a Gasket kit and is a separate order. The Fuel Injection Pump has to come off to change it.
When I changed mine I did not like how thin the Stock Gaske is and used it as a Template and made another gasket with thicker Gasket Paper.
There is also a Plastic Oil Feed Line that goes from the Block to the Fuel Injection pump. That can be replaced as a separate part and you need 4 copper crush washers. The plastic can get old an Crack.
The M type Fuel Injection Pumps have a Cover on the side of the Pump that has a Gasket that can Leak Oil. Another item that shows as a separate part.
The most common Oil Leak spots are the Block to Pump Gasket, the Bottom Pan Gasket, The M Pump Side Cover with the Throttle Shaft O-rings last.
If you mess with the 13mm Nuts on each side of the Fuel Outlets/Delivery Valve Holders you will change the amout of Fuel each one of those Elements pust out. So the Elements are not something to mess with unless your absolutly have to as they are set on an expensive Calibrating Machine.
With the exception of the above the other areas that might leak Fuel can be taken care of with out a whole kit.
The Delivery Valve Crush Washers can be bought each.
However, if you insist on a complete kit write down the Numbers on little Plate on the Pump and take it to a Bosch Fuel Injection Shop and ask them the Cost and Availability of a gasket kit.
In the Mercedes parts catalog they show a Gasket Kit for the Fuel Injection Pump. I don't know how complete it is.
You can get a Valve Kit for the Fuel Supply/Lift Pump; it has 2 Valves, 2 Springs and 2 Copper Crush Washers.
