Hey Ya'll, nother new guy to the site.
Background: 2003 350 7.3L new off the lot 10/02, auto, 4x4, 176000+ daily driver 40-50 miles per day plus used to haul hay, firewood & my horses. Mods are few: straight pipe, B&W goosneck, K&N filter. Few challenges: She likes to eat batteries, 2nd alt. wore a hole in the top fuel line, bad glow plug or 2...all covered under warranty thankfully...just changed the factory thermostat last weekend at 176000...dunnno if that is good or bad, any thoughts? Also, the orig. thermo. has a tiny hole off to one side, new one don't, any idea what the hole is for?
