Diesel Fuel Lift pump
Is the injection pump the only fuel pump in a TDi ? A Haynes manual says so. I thought there was a lift pump in the tank to push Diesel through the filter. Book says TDi injection pump sucks Diesel from the tank through the filter just like my old Rabbit !

After much disagreements and online screaming [you know-WITH CAPS ON] i realized the lift pump doesn't even work all the time. It is only there to circulate fuel when it gets too hot, it then circulates it through the cooler. This was because i was converting a PD to veg oil, and was trying to figure out if it needed an extra lift pump for the VO. In the end i just installed a lift pump with a switch so that the person could switch it on when there was a lack of power.
