850CI - oil pressure sender / fuel pump relay
 

Trying to help friend find info on his 850 after this site was so helpful with my classic...

Two problems:

Hunting down oil leak after sending $$ to replace head gaskets. Trying to eliminate easier items like any oil leaking accesories/sensors. Ideas? Where is oil pressure switch located on 850Ci?

Intermittent fuel pump(?) on one bank. Assume there is a relay involved. Where is it located?

Searched a lot but surprised not seeing much on 850's

Thanks all!
