New fuel pressure regulator and fuel filter for Mercedes Benz 

ML 320, ML 350, ML 500

Fuel pressure regulator and filter has 4 line connectors and will not fit early models ML not listed here unless you purchase new  fuel line hose kit. Early fuel filters have 3 lines. New ones have 4. We are selling one as pictured

the line diameters are:

bottom @ 9.5 mm

side (lower) @ 8.0 mm

vacuum line connector (small line) @ 4.0mm

upper/top @ 8.0mm

You have to replace the fuel pressure regulator IF your car blows raw gas out of the exhaust.

These new fuel pressure regulators have neoprene rubber diaphragms. Old design ones - like you currently have on your ML - still have gasoline resistant rubber. Great stuff, but they are not Alcohol resistant. Most gas stations carry gasoline with some %-age of Corn alcohol. This is the cause of the damage to the pressure regulator. Whiskey in your gas tank...

Vacuum  from the engine on one side of the fuel pressure regulator controls the amount of fuel going to the engine. When the diaphragm gets ruptured - fuel enters the engines intake manifold through the vacuum line port. This will cause poor performance and makes driving the vehicle nearly impossible.
