Need help with fuel supply and return line plumbing on your Doosan Bobcat D18 D24 Engine? Here is a simple image to explain.
Fuel Supply From the Tank: Hooks to the metal line in the illustration
Fuel Return to the Tank: Hooks to the plastic fuel venturi
Fuel Return from Injectors: Hooks to the small barb located near the Fuel return to tank connection
If the two lines are reversed, it may pressurize the fuel injector return line and blow the lines off of the injectors
The D34 Doosan Bobcat engine plumbing is very similar and the above image can be used. The above image is a D18/D24 pump
