Tony240ZT Posted February 8, 2002 Share Posted February 8, 2002 The drain plug hole is tiny. It's 1/2", but that doesn't leave very much meat for a good sized ID. I would highly suggest drilling and taping it to a 3/8" NPT. I'm going to do it in the morning. I have a 9/16" drill bit and the 3/8 NPT tap. Also have a 90 degree 3/8 NPT to -6AN, a -6 push on fitting and some cool red hose. Quote Link to comment Share on other sites More sharing options...
