    Does a fuel sending unit need to be 'rust inhibited' before re-installing?

    Hydro-blasted the (original) sending unit to remove 30+ years of accumulated rust, and now it looks really good. With all the rust gone, I was wondering if the unit needs to be sprayed with some sort of primer, rust inhibitor, or epoxy coating to prevent it from getting nasty again.. Or is...

    Engine Issue or Torque Converter issue?

    Finally got around to taking the truck out after the last problematic run I posted about. This time I was driving during the day, without rain, and with the bad injector replaced. I googled the issue I am having, and some results point to the engine, others say torque converter. VEHICLE...

    Fuel is accumulating on the Valley Pan

    I have a puddle of diesel fuel that builds up on the valley pan. (then ends up dripping off the starter) I am hoping to find where the leak might be coming from. (Puddle only after the engine has been running, and there are no signs of air intrusion) There is some grime and grease built up on...

    NAPA discount

    Let me know if this is inappropriate for the forum.. and I will remove If you have a AAA membership, you get 10% off at NAPA. But during October, the regular AAA discount of 10% DOUBLES to 20% on purchases both online and in-store. So for those of us that get parts at NAPA, 20% off keeps a...

    About to change the rear diff fluid..

    I don't know when/if the the fluid has been changed in the limited-slip rear diff on my 94 E-350 w /250K miles. Aside from metal 'slivers', are there any tell-tale signs of trouble I should look for? On the refill.. Is there any truth to synthetic causing leaks due to cleaning out old sludge...

    Wanting to add additional brake lights... Can I just tap the existing circuit?

    I want to add another set of brake lights to the truck, but I read changes in the resistance of the brake light circuit can affect torque converter lockup. Is the lockup issue only when a bulb is burned out or missing, or will additional bulbs also affect the circuit? As far as a solution...

    Injector Knock? or something else?

    Drove about 50 highway miles yesterday, then turned off to go through a town. When I started from a stoplight.. I heard a weird "ticking"/"knocking" noise that can best be described as sounding similar to a "bad gas knock" or a piece of metal hitting the radiator fan blades (which it was not)...

(see the first picture) I've read that not having them can cause broken lines, fuel leaks, and other related headaches. Anyone...

    New/Remanufactured injectors vs Ultra-low-sulfur diesel (ULSD)

    Just wondering.. Does ULSD affect new and reman'd injectors as much as the original injectors that came with our engines, which were designed for a different fuel formulation (and level of lubricity)? O-rings and other parts have gotten better/upgraded materials.. so I am wondering if...
