Hi, I just purchased a used metering pump off Ebay. Will use it for spare parts. It is electronically controlled with 2 plugs. However, it only has 2 output ports.
I thought all 13b engine had 4 oil injectors. Only engine i know that uses 2 injectors is the 12a. Can anyone tell me what this came off? Thanks for the information.

 

the early FD unit is same as the s5 but only two output ports
