Re: [diesel_mercedes] Newbie question #56 1978 300D fuel pump

 

Rodger, The people using blends in Powerstroke diesels came to the
conclusion that including diesel in the mix causes the blend to create
waxes. I assume these gummed up the injection pump. Bobby

Rodger, I have a 79 300CD, but am not an expert. I would remove the
fuel return line from the last (back) injector. Get someone to crank.
You should see copious flow. If it does both the lift pump and the
injection pump are working. Another likely problem is the glow plugs
and their power souces. I would not use a blend, but must people
using them include some RUG (regular unleaded gasoline). Bobby
