Title: Bosch VE Pump.....Break In????
Post by: ftm1776 on July 11, 2014, 07:05:02 pm

After complete and correct rebuild to spec, does the VE pump "break in" so that it's performance slightly improves as parts settle in and loosen up a bit???

i.e., does it get a little bit more efficient at delivering the fuel so as to effect economy???? assume rebuilt injectors as well.

      My return-to-idle got better after a few miles of driving on a fresh reseal.       Not a "break in", just a slightly sticky control collar inside the pump.

Injectors definitely take a bit to settle in. Not so sure about pumps.
