Will look today. Unfortunately this is a Chinese one and the instructions are impossible to understand!
Can you follow the line to see if it is the fuel supply line and not the return.
Well you have not answered any questions. You need to determine if you are connected to the supply or return line and the specific location. Is this a factory 200TDI or a conversion? 90 or 110?It's a 200tdi
You need to go and look and follow the lines.Currently it's splices in as seen in the photo, I'm 99% sure it's the supply line.
