These fuel injection systems are now over 50 years old!
It is critical that these aging fuel lines and injectors on 1975 Mercedes V8 engines be inspected and probably replaced.
Problem & Solution
I will specifically address the issues that can be caused by ruptured or leaking old rubber fuel hoses and early engine failures caused by old, worn-out fuel injectors delivering too much fuel, causing excessive piston ring and cylinder wall wear and diluting the engine oil, which leads to excessive timing chain, camshaft, and sprocket wear.
