WTB Tii Pressure Relief Valve 13511257555

[MarkC]

I need a pressure relief valve for the return on the back of the K-Pump

BMW Part #13511257555

(#8 in the pic)

 

Paul Wegweiser found what we  believe to be the last "smoking gun" on my car, the one that was on my car is all mangled up (to put it mildly).

Sadly, this is a NLA Part.

Paul used his known good valve to test everything out, but he needs to keep that one for his shop.

 

OR, if you have any cross reference part numbers for it on other cars where they may be available, etc.

 

OR, if you know the specs of it that I can have a good friend (engineer w/ a manufacturing company) look into replicating it.

 

OR, what a solution is with readily available parts.

 

TIA
