Talk to Big Joe at kewlmetal.com
He posted on another forum that he uses a threaded aluminum fitting and JB Weld. He also mentioned that he's done a few with no problem and has pictures.
A different poster said he drlled out the plastic nipple and replaced it with a metal fitting. He had to remove the quick disconnect and replace I with fuel line and hose clamps.
