    Leaking fuel line

    If there is a slight difference in tubing diameter do consider that 10mm and 3/8 are very close in size but not close enough to be compatible like 8mm and 5/16. If you had dimension related issues it was likely due to metric vs standard incompatibility. For those trusting their these lines are...

    M923a2 Coolant System Drain and Flush:

    The pre-diluted extended life coolants ARE 50/50 ethylene glycol and water with corrosion inhibitor. You MUST not run any coolant without corrosion inhibitors. If you WANT conventional coolant hit up your local Caterpillar dealer and ask for Cat DEAC coolant. It comes pre-diluted 50/50 and has...

    Leaking fuel line

    Nylon may have questionable compatibility with some diesel fuels. https://www.sae.org/publications/technical-papers/content/2006-01-3326/ I don't know what diameter you're working with but this stuff resist just about every fuel at all temperatures and in sunlight...

    M923a2 Coolant System Drain and Flush:

    If you don't know the history of your coolant then you must change it. If the system is in good condition, drain it, fill it with fresh water, drain it, and fill it with new coolant of your choice. Use the OEM coolant if you have any concerns about compatibility. Otherwise you'll need to do a...

    The 831 means it's for an 8 cylinder engine and has the larger 0.31" plungers.

    Good video for restoring an old battery with a welder!

    I have opened failed batteries. The plates are usually broken apart and sitting at the bottom of the cells. I don't think a welder can fix this.

    HMMWV (GM7) Turbo Question......

    Turbocharger bushings are meant to rotate in the housing. This means there is clearance between the shaft and the bushing and clearance between the bushing and the housing. All of this clearance makes them feel loose. As long as you can't make the compressor touch the housing the turbo is good...

    12 Volt to 24 Volt step up power supply question

    NewMar specializes in this. They are a commercial duty option so expect to spend $400-800 depending on the size of power supply you purchase. https://www.newmarpower.com/ Furuno has similar products. Check Mouser if you know more about what you need...

    Best sealant/glue for ducting

    Avoid silicones as they'll make it impossible for the correct bond to be made after the silicone fails.

    Best sealant/glue for ducting

    Epoxies bond well to ABS. I would consider using some fiberglass tape to fill the gap and using an epoxy resin such as West System, available at your local boat hardware store. If you can close the seam use an adhesive polyurethane sealant. 3M 5200 is a favorite but not UV resistant. Your local...

    M1009 Fuel lift pump to fuel filter hard line replacement

    J30R9 is good. It has a Viton tube with chlorinated polyethylene cover. The R10 hose has a Viton cover. CPE is often used for electrical wire insulation and has good durability under hood.

    803a fuel rack sticking problems, are there options before pulling the covers off?

    Methanol (Heet at your local auto parts store) can free up stuck plungers and racks on installed injectors. Pour it all over anywhere you think it can access moving parts.

    Charging/Maintenance and Alternators

    What is the goal? In temperate climates starting batteries last 5-7 years. In desert climates it's 3-5 years. Cold climates are a bit more complicated. Does anybody have evidence of their preferred charging system extending their battery life beyond 5 years? Was it worth the investment?

    It is the fine spline which I believe to be 32 teeth.

    Unfamiliar Coolant

    Other brands of OAT coolant mention 10% contamination tolerance meaning you can safely leave behind 10% of your old coolant. If you do a phosphoric acid flush you'll want to purge with fresh water.

    Tell us why you think it would hurt your cooling system so we can understand the source of your information.

    Unfamiliar Coolant

    Don't mix coolants. You can't judge them by the color anymore. Modern coolants are all organic acid based. Inorganic acid based coolants are available in some heavy duty applications but not from the auto parts store. That Starbrite cooling is organic acid tech like modern coolants but uses...

    M1009 Fuel lift pump to fuel filter hard line replacement

    FYI, the hose clamp I linked is an example only. You'll have to measure your hose and select the specific diameter clamp.

    MEP-802A - can this thing function with a 60' exhaust run?

    When hanging your pipe keep in mind that you're going to have to accommodate ~1" of growth over a 25 foot run assuming the pipe is well insulated and 600°F over ambient. The key is to have a fixed hanger at the engine end and the remaining hangers are floating to allow for this type of growth...
