The other day I was considering the purchase of a used fuel pump from an
e-bay seller, ID: 'karmanvan'. I had e-mailed him to ask the bosch part
number on the pump to determine if it was the correct part for my vehical.
He informed me that Bosch had different exact-match pumps with different
last 4 digits of part number indicating where they were made, all exact
matches for the pump that belongs in my van.
Smells like a skunk to me. The Bosch part numbers I have for all of the
electrics in the van (Thanks Joel) refrence only a single number for the
fuel pump. Ends in 016, if memory serves. Gentleman informed me the same
pump built in france ends in 011. Another for Italy.
Why would Bosch have the same pump made in different places and give it
different part numbers?

That sounds like a pretty interesting job. I like the pilot that hovers
all day as part of his advanced training. Punishment for something, I
guess.
I'm also curious about predicting a transmission failure in a helicopter.
How do you let it happen without catastrophic consequences to man and
machine?

That went just a little over my head. Mind explaining with a little more
elaboration? Bolts that are made to stretch?
Off to camp at Guadalupe state park this weekend. I hope to hell that
the van makes it there and back. Had a couple of maintanence items I wasn't
able to tackle (afford) before we leave.
