Re: glow shift
Well since you are a diesel tech I will let you in on a secret. That mechanical fuel pump you refer to is found on every powerstroke 7.3 from 94.5-97. They changed over to a dead head electric pump system with the body change to the superduty.
That "special thread" you are asking about where the schrader valve is located on the fuel pressure regulator, which is bolted to the fuel bowl, is 1/8" NPT.
