External Feul Pump..

["Ron J" <ron@xxxxxxxxxxxxxxx>]

Hi all,

Due to definate ICV problems, rough starts, surging idle, and loss of feul
pressure during driving, I am looking at changing the following in my car.
The prices beside them are the best I have found so far for an 85 535i, all
bosch parts and apparently new.  Most from Partsbin.com, linked through
bmwworld.com

ICV $93.29 (bosch)
In tank feul pump $104.49 (VDO)
external feul pump $127.87 (bosch)  $117.76 (Pierburg)
feul pressure regulator $39.22 (bosch)
cold start valve $62.26 (bosch)

I have a few questions.  First.. Does anyone know where I might find them
cheaper?  Secondly, what is the difference between the bosch and the
pierburg external feul pump?  are the interchangeable or does it matter
which one was in the car in the first place?

Thanks in advance for the info.

Cheers
