01 Bug with 1.9 and running bio. Has new turbo and manifold, cant get it to accelerate past 3k Put clear lines on fuel system to see if its getting air and return line has a lot of air going through it. Any suggestions.
The plot thickens....or rather, the grease thickens. Grease buildup can damage the injection pump, injectors, and valves through sticking and buildup. Back to the bubbles, you still have an air leak somewhere. Worst case it's somewhere on the pump. A bad seal could be letting air in. Do you have any leaks or stains on the injection pump body?
