    Can vegetable oil be mixed with diesel and or wmo?

    I already run a blend of wmo in my rear tank and diesel in my front tank. My dad thought that I could use vegetable oil and proceeded to collect about 3 gallons from his friends neighbor. Can I add it to either the diesel or wmo tank? Obviously I would filter it first and stuff, but I'm...

    Coolant temperature switch and coolant overheat switch fail at the same time?

    Yeah looking back i should have made it clear that I was also talking about the temperature switch for the fast idle system. I often find myself thinking faster than I can type and not realizing I didn't type what I thought I did.

    Coolant temperature switch and coolant overheat switch fail at the same time?

    Ok so I was specifically talking about the coolant overheat switch and the coolant temperature switch for the cold fast idle solenoid and cold timing advance. The one on the front driver side cylinder head right above the exhaust manifold for the overheat switch. And the one in front of the...

    Coolant temperature switch and coolant overheat switch fail at the same time?

    A few days ago I lightly pressure washed my engine bay. Held the wand at least a foot away except right by the fuel filter and number 1 injector to clean out some fuel/oil that accumulated there. Since then I've had some electrical issues. Both the coolant overheat switch and the coolant...

    Fuel filter light comes on fuel pressure reads good.

    Ok so I figured it out. Long story short the fuel filter had actually gotten clogged. So, in case anyone is looking for it in the future; even if you have a good fuel pressure reading you can still get the fuel filter light coming on if your filter becomes clogged. Now it depends on where you...

    Fuel filter light comes on fuel pressure reads good.

    Now its coming on under really any kind of throttle. At first when I started driving it today it would only come on around 2100 rpm and now its on at pretty much anything above idle. Im going to change the filter just to rule it out, even though I don't think its the problem.

    Fuel filter light comes on fuel pressure reads good.

    I forgot to add that its 1991 f250 7.3. Also it doesn't lose any power when the light comes. It can actually keep accelerating.

    Fuel filter light comes on fuel pressure reads good.

    Just installed a facet duralift 40223, the 9-11 psi pump with a weatherpack connector. Now my fuel filter light is coming on under heavy acceleration. Before it never came on with the mechanical pump. I did read in the other forum threads that that light means a vacuum is being pulled on the...

    Can the mechanical fuel pump be left on temporarily after installing an electric lift pump?

    Thanks for the input guys. I ended up just waiting for the block off plate. If I get another truck in the future I won't think twice about leaving the mechanical pump on temporarily if I have to. Sounds like its not a big deal based on several of your guys experiences.

    Can the mechanical fuel pump be left on temporarily after installing an electric lift pump?

    Im installing a facet duralift pump in my 7.3. My question is can the mechanical fuel pump be left on unplumbed temporarily? Without fuel running through it to keep temperature down could the diaphragm overheat and fail puking engine oil out the side? Id really rather not find out while driving...
