Hi guys.
The question is regarding a 10/76 donor and a 1/78 patient.
I see on the OEM that the (eg. fuel pump assembly from the 1976) says up to 9/77. My question is are they physicaly interchageable, just updated versions?
Also the electrics, would everything just bolt in place if i just transfer them to the 78 shell?
I think they are the same but cannot confirm. Euro to US spec may have differences since early euro cars only have one external fuel pump.
BMW part# 16141178751 supercedes all applications from 1976 through late '87 IIRC.
'84 Euro 635
'88 M6 (Gone but not forgotten)
Here is the fuel pump example
