BMW check valve ???

[asatxj]

Does anyone have pix of the install of the BMW check valve? My 91 has two lines to the FI rail that are the same size so info on which line and where it has been installed would be most helpful
TIA

I have no idea what you are talking about.

Perhaps I should say "fuel pressure check valve" it's a BMW part that goes inline and maintains fuel pressure when the OEM (which is a PITB to replace) is bad.
Was that more descriptive?
