I’m struggling with a retrofit fuel drain on these 800 series generators. I purchased some 3/4” bulkhead fittings with 1/4” NPT internal threads. The nut size for these bulkhead fittings is 1”. I also purchased some 3/4” ID neoprene flat seals and some 3/4” ID flat washers to back them up. The neoprene seals that I have are .125” thick. I’ve seen the retrofit kits and I’m just trying to buy my own parts to duplicate this retrofit. But no matter what I do, they leak. I’m using a neoprene seal and 3/4” ID flat washer on the inside and the outside. As soon as I tighten up the nut on the outside, the neoprene seal just squeezes out past the 3/4” ID flat washer. I’m open to suggestions ![Unsure :unsure: :unsure:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
