I take it that you have pulled the oil pump off the engine for some reason and now want to make sure that it will pump oil when the engine is started . If that is the case take the end cover off the pump body and fill all around and in the teeth spacings with Vaseline or clean grease. This fills up the spacing between the gears and the body where the oil is moved and creates the vacuum necessary to suck the oil up from the sump. The grease or Vaseline will melt down and intergrate with the oil.

How do i prime an oil pump on a 460 ford engine?


If it's lubricating oil, you don't need to prime, it is self-priming. If you have a diesel engine, and you are speaking of the diesel fuel and filter pump system, then you should have a manual pump on top of the fuel filter that when pushed down and released, will suction fuel from the tank and push through the filter and to the injection pump. Although, most large trucks use an electric "lift pump" which does this automatically. So if you can be more descriptive of your problem it will help us to help you.

Bmw diesel wont start


I'm guessing that you got an air lock in your fuel system as a result of your changing the fuel filter... I certainly don't know about a BMW diesel, but in most semi-truck engines, there is a priming pump just for the purpose of getting the air out ... and the fuel into.... the fuel system. I've even been known to fill the filters with diesel fuel before screwing them onto the base.. This is risky because of the possibility of allowing some foreign, unfiltered debris to get into your pump and/or injectors, just because of your putting unfiltered fuel into your filter... Check and see if there is some kind of priming pump close to the filter. Also, a possibility is that you may have an electric fuel pump.... as to where all you may need to do is loosen a fuel fitting on the pressure side of the pump and filter.... and allow the electric pump to purge the system of air.. I confess to my lack of knowledge on your BMW.... but, I do have some basic understanding of most diesel systems... Good luck..

2008 F250 OIL CAN LIGHT ON


There should be a section in your owners manual for symbols.
On diesel models that symbol should be for a problem with the fuel system if you have the words "low oil pressure" that show up in the display.

No, the injection pump is the fuel mover. There should be a means to manualy prime the system. Look for a hand pump with a knob . Unscrew the nob and pump it up until iy pressurizes. The lock the pump dow and hit the key. Good Luck

04 f250 6l diesel cranks but will not start when cold.


it seems that because it sit's for a while that perhaps it's losing it's prime. if ythis happens generally you will have to reprime the fuel system. in a diesel system you also have glow plugs to help ignite the fuel. check to make sure your glow plugs work, but i would start with whether you have proper prime in the fuel system.. please rate this
