bird watcher - Thanks for info, as might come in handy sometime. My TC26 has fuel filter in bowl just before injector pump, so probably doesn't have one of those screens like in your truck. But, who knows? Maybe has screen too. Anyhow, good info to have.
Jim - What's the drilling of ROP's? Roll over protection? I've worked with a fair amount of tubing over the years, including space frames for racing cars and other stuff, and drilling holes can affect strength (and result in failures) if not done right. If there's a thread on this, and you give a link, I'll take a look at it in case I can help.
