Quality product
"I have a 7. 3 PowerStroke van with DIY custom T4 turbo kit. I ordered this adapter If i bother to deal with my block return line. (7. 3 PSD has a 7/8 freeze plug in top of the block that can be used as an turbo drain. 94. 5/97 OBS has a mechanical fuel pump in there. 7/8 is the same diameter that 5. 9 Cummins uses for turbo drain. ) Nice quality product."
