Title:

W123 proper diesel lift pump?

Text:

I am ready to clean/change fuel filters on my 1983 300d and dont want to rely on the primer pump [hand operated] and saw where a lift pump would allow me to close up the circuit after the change of filters and turn on the pump and let the air bleed out mechanically. would anyone know the right pressure these lines should have on the way to the injection pump? there is a video of a heated sump and pump for this but they were no longer available for sale so it semms i have to piece these parts .
