THe OM616/617NA transfer pump (lift pump) is Bosch FP-K22MW2 or ten
digit 2 445 103 010. MB never did provide a kit in the USA, and I don't
now if Bosch ever did. I am thinking in the RTW, that a kit may be
available. has anyone ever seen a kit or have foreign contacts to
inquire about a kit for the pump?
Nothing turns up on fleabay except a pump body. That is the one part I
don't need.
The good news is that I took the 240D out tonight for a 2 mile run, and
now it runs fine. The apparent warning I had, but was unable to
attribute to any cause, is that at idle, especially when cold, the
engine would randomly miss at idle. The pump seemed to function
adequately at higher RPM, as on last thursday I ran it probably 60 miles
or so at highway speeds. It is the opposite of a obstructed filter, or
air leak which show up first at high speed or starting.
I was able to pump up fuel easily with the hand primer. It filled the
hose to the filter and I bled the air out there, then tightened the new
banjo fitting. I have been hoarding new clear fuel lines since 1999. I
put the one from the transfer pump to the filter on with the used pump.
Unfortunately the hand primer leaks when used. THe original was ok I
think. I may change that some day.
Has anyone seen exploded drawings of the pump or parts drawings? I'd
still like to figure out how they are made to see if I can repair the
old ones.
