Here are 2 part # I came up with Bosch # 1467010059 or DGK121 , google either one and it should work. Pump removal is pretty straight forward just remember you need a gear puller to get the gear off to remove the pump and I always put a rag in the hole when I remove the nut so it doesn't fall into the gear case.

 

Wow, you can even get one at malwart, place must of changed a lot since I last darkened their doors in 1996...

Looks like The Hungry Diesel has a DGK-121 for $35.

Thanks for the part number!

 

If you have an injection pump rebuild shop near you they should have the kit on their shelf as well. and as far as wally world it would ship from a different seller, they would not have one in-store

 

I've not had the time yet to address this issue and am getting by by manually pumping the lift pump until the IP starts to weep, then it will start. Fortunately I've not really needed it much lately.

Until my hot water heater went out and I had to make a run to town for a new one.

But when I went to prime the IP my lift pump lever was down this time and barely moved, maybe 1/2-3/4". And once running it's still limp but I can feel it hitting the lobe.

So does this mean my lift pump has gone bad too now I guess? When it rains it pours...

 

Well this morning it was stiff again and pointing back up where it's supposed to.

My lift pump lever that is...

 

The lift pump thumb lever will only work well if the cam lobe inside the motor is in the right place.
Sometimes bumping the motor over a few times will make it so the LP lever feels and works like you want it to.

 

That must have been what happened. It did fine yesterday hauling firewood.

 

Mine sat for 6-7 years. I did the lever on the lift pump. I think maybe 40 pumps. It fired up!

 

The lift pump priming handle should never be down when you initially try to prime the pump. Last step in priming is to raise the handle to the upper most position. It should stay there on it's own. If it falls down on it's own, then something is wrong. It may not be serious (I don't know if the linkage rides on the cam), but something in the LP is worn if the handle falls on it's own.

 

It's got to be on the right place on the lobe on the cam from what I've read. If not a small bump with the starter.may be the cure. I guess I've always been lucky!

 

Your a 100% right on positioning the cam for priming. The point of my post was that after you prime the system, always raise the handle to the uppermost position. It should stay there and not fall down. It gets the priming linkage out of the way of the pump diaphragm.

 

I think the piston style lift pumps have a separate priming pump and don't depend on the position of the cam.
