This is how I fixed my FN250C porter cable trigger assembly. It was leaking air through one of the o-rings, most likely the yellow ring that feels like a soft rubber band. I recommend replacing the entire part instead of trying to track down the 5 separate o-rings. I bought on amazon/ebay, but there are other online resources. You will need to track down the part number by referencing the model number - some models will have the same part. Also, some parts will be replaced by new parts and numbers, so the numbers might not match up.

I did NOT disassemble the new part for fear of destroying the yellow o-ring in the back. On the old part it was soft and came apart quickly which means that air could pass by it.

The part number i bought for this particular install:
Porter Cable 64762000 Trigger Valve Assembly
