Thanks again for checking back. No, I can't reinstall everything back because I can't get the union nut into the filter base because it's stripped.
As far as bypassing the filter, there a lot of hoses/pipes on this filter. On the left side is the inlet from the Racor. On the right side is an outlet hose to somewhere (fuel pump?) and an inlet back from somewhere. On the top of the filter is what looks like a return from the injectors attached by a banjo fitting to the fuel return line back to the tank. How would I bypass this? I've been looking at the diagrams and reading about diesels but haven't found anything good about it.
