|I'm working on a bone stock 67 bug and replaced the fuel pump.
After replacing the pump the engine is now running rich. If the new pump builds more pressure than the old one could it cause this rich condition?
The pump is the only thing I changed.
I'm saying it is running rich based on my highly technical sense of smell and the lingering smokelike vapor coming from the tail pipe when I turn off the engine.
