What is the difference between that and item number 0000900210 to make the $30 spread?

Do they both include the in/out valves?

There is a ten dollar spread between the kits, due to kit part difference..

They both include the in/out valves.

Correct me if i'm wrong. The lift pump can have diminished performance before it completely fails.

Yes, but you must fully understand the MB diesel fuel system for diagnostics.

Question: If both PNs for the repair kit are the same, how can you tell them apart? I ordered a kit with number 0000900210 from the dealership using for my 78 240D, but it does not specify which springs. I would think it is right since they looked it up for a 616.912 but the contents do not match what came out of my lift pump. My lift pump is FP/K22MW7. Curious if there is an alltogether different kit for mine?

Rule of thumb, if the lift pump repair kit parts fit, and function you are OK.

The confusion is some times due to the antique MB design - engineering PARTS management system.

There are (in the EPC) some identical assemblies with eleven different design compatible rebuild - repair kits.

It may have been an internal turf war and/or communication issues that caused problems.

Not all of the parts are available from Pelican. I'd call before placing an online order....most upsetting

Sorry.
We dropped some of them from the catalog because they are NLA.
Yet EPC and MB inventory show valid, and in a few cases in stock.

It is not until you try ordering that the MB error (days later) becomes evident.

Tks for these notes - am in process on trying to diagnose a 'general loss of power' at load... I suppose doing this maintenance on a 300k+ is a good idea?? !!!!!

Thinking' also about nozzle replacement, fuel tank screen cleaning - these things never done.

IMO all of these are a good idea at 300K.

did the design of the lift pump ever get revised or something ? on my '80 and on my '85, they both flow "normal", like they both always have, which is not particularly alot, even with all tanks and screens and filters and things all clean as new......on someone's '83 i was working on, i couldnt help noticing it was pumping fuel through "like a firehose" and you could quickly fill a gallon jug with fuel from the return........same thing on someone else's 60x series i was working on......are mine both just old and weak and need rebuilt ? or is there a difference on certain years ? i had always understood that this old fashioned mechanical pumps were almost indestructable, but after seeing this post about kits, i can appreciate the need for the components to be new and in order, and not 300k + ......

It sounds like you need at least this valve kit to restore the flow.

Really anything reasonable to rekit after a lot of miles that saves a road breakdown is worth the preventative effort in general. A road breakdown away from home can land up very expensive in comparison.

In fact so expensive on occasion there is no comparison. For the few times it has occurred over my lifetime it usually also consumes a days time.
