What It Is
A triangular socket, machined from steel hexagonal bar stock, built to fit the triangular anti-tamper bolt on the Bosch VE injection pump.
Why You Need This Tool
This socket is required if you want to adjust the pump timing or replace the fuel temperature sensor. It removes the screws holding the top pump cover in place, giving access to the sensor underneath. It's considered essential for any serious TDI tuner working on VE-pump engines.
