I have a 914 with a 3.0l six and PMO carbs. The gas smell is unbearable, especially when the car is in the garage. My wife is about to lose her mind. What do you carb guys do to limit this? Would running the engine with the fuel pump off, IE running out of fuel help with this situation?

I would check all hose clamps to lines, filter, pump. My new pump and filter came together with hose and clamps....the provided clamps leaked badly. Its been two years now and no gas smells. PMO's, single fuel line, low pressure fuel pump, inline fuse.
