I have a 1997 292 regal . I have been using one of the rubber nozzle quick connects for the pump out for ten years now. Does any one know of someone who makes a threaded nozle that will fit this paticular fitting. Of the three sizes i have found on the market not one fits. I believe mine is 1 3/4 inch by 16 threads per inch.. Fine thread. Am i going to have to take the deck fitting out and replace it ? Thx for any help Chris
