Cracked Fuel Pump

[DonJ]

Ever see a fuel pump do this?

Sorry one is a bit blurry - my batteries died before I could ge a better pic.

This came out of my 1991 535i.

I replaced the pump yesterday and this is how it looked when I pulled it out.
This might very well be the reason for the intermittent starting problems I was experiencing - especially when the weather cooled down a bit (I have an earlier post on this forum).

I'll finish up tonight working on it and I'll run it for a few days and see what happens.

The pump is very easy to replace but I was also in the middle of changing out the Crank Position Sensor and I don't have the cooling fan put back on yet.
