    WANT TO TRY A LIL BUDDY HEATER TO WARM ENGINE

    Cubey, I'd bet that fire wasn't from a lil buddy, more likely from an electrical short, could've even been from a block heater shorting, most likely a gas engine, but I get your point and fire danger would be considered. I've used one (heater) inside my camper for a few years and love it but...

    WANT TO TRY A LIL BUDDY HEATER TO WARM ENGINE

    I have an old 6.9 F350 Dually crew cab with a 12' camper. I love the old truck and it runs great, I use it maybe five times a year for 3-14 day campouts. The only problem with the truck is that it hates cold starts, it'll start fine but likes to smoke until it gets warm. If I put it on the...

    Thinking Of Plumbing My Two Tanks Together

    Mulochinco, Thanks for the kudos, I've found that I can accomplish a lot with a mig, drill press, drill, grinder ect. Our setup looks very similar, both use 1/2 inch hose, my fittings are 1/4 inch ID looks like yours is probably larger ID. Can't see how your sealing is actually done but it looks...

    Thinking Of Plumbing My Two Tanks Together

    Franklin, That's one reason for only a 1/4 inch hole in my fittings, it's large enough to transfer fuel for engine use but small enough to not transfer fuel to fast while filling and cause a back and forth fill need. Because the front tank hangs down lower and will need to fill about 3 inches to...

    Thinking Of Plumbing My Two Tanks Together

    Finally got time to sit down and finish this thread. I hate it when threads end before the project is finished and we're left hanging, so here's my ending. I finished the project several weeks ago and I'm really happy with it. Replaced all the fuel lines from the steel line that crosses from...

    Super smoky startup fixed!

    Only to pass thru on the way to a remote area. Leaving in about a week, 455 miles to elk camp, I take the back way, largest town is Burns Or. about three stop lights. It will be nice to have that option like when I took the wife to arches in Utah last year. So maybe I had a pinhole up by the...

    Super smoky startup fixed!

    WRENCHHORE, I think you're right, the air in the lines lower's pressures and then the injectors just don't pop right. I really don't understand how a leak 8 feet away from the injectors can cause instant smoke and rough running, it's like the air finds its way through the line to the injectors...

    Super smoky startup fixed!

    So I've been chasing this problem for several years, I've posted about it several times. Startup on my "86" f350 6.9 was smoky beyond bad, it was like a locomotive. I only use the truck for excursions into remote areas so I just kept putting up with it, it only did it once a day. It would...

    Thinking Of Plumbing My Two Tanks Together

    Thanks for that post MULOCHICO, it gives me good confidence that this is a viable way to eliminate the FSV and 1 sensing unit (I'm tossing my rear), and a hand full of connections. The OEM FSV was built super good but after 39 years I know it's getting close to death and I'm pretty sure a new...

    Thinking Of Plumbing My Two Tanks Together

    Thanks for clarifying how that valve works, The valve looks old and I really doubt it even works, they used cheap rubber hose that was split on the end, so I like the idea of just taking it out and replacing with a good hose, I think I'll try to run it up along the filler neck and punch it...

    Random surging while driving

    Just hoping ISPKI would write the last chapter of this book!

    Thinking Of Plumbing My Two Tanks Together

    You're right Goat, got the front tank out and there is one there also, except unlike the rear, the rubber tube lays across the top and then runs down to the bottom of the frame where it attaches. On the rear it attaches at the top of the frame, it was aged out, the end was split and the plastic...

    Thinking Of Plumbing My Two Tanks Together

    Well I just finished dropping the rear tank, I started by taking off the trailer hitch framework because as others have said it hangs to the inside of the frame and the tank flange won't slip past easily. I also used a hole saw and put a 3" hole directly through the bed over the hose clamp that...

    Thinking Of Plumbing My Two Tanks Together

    Thanks ISPKI, This may sound almost stupid on my part but I really don't have any idea how big my rear tank is, when I bought the truck from my cousin 35 years ago he told me that it was really small, and after 50 miles tops it has the needle buried below the E mark, so I've just always treated...

    Thinking Of Plumbing My Two Tanks Together

    Thanks for the input! The issue of overflowing fuel while on a steep slope is something I hadn't considered. So I leveled the truck and took a bunch of measurements and then made those into a drawing on CAD where I could rotate the image and see what would happen on different slopes, I got a...

    Thinking Of Plumbing My Two Tanks Together

    IDIBRONCO, I'm not following you're reasoning, and I'd like to, I don't want to make a blunder here. If I'm only pulling fuel from the front tank and only returning fuel to the front tank, how could it overflow either? the rear tank will always seek the same level as the front tank rather it's...

    Thinking Of Plumbing My Two Tanks Together

    ASMITH, you're getting it pretty close, I plan on installing a very small line between the two (5/16), when filling up it wouldn't be transferring much fuel thru the line, I would just fill both tanks using their own spouts, just like now, a small amount would gravity feed to the other tank via...

    Thinking Of Plumbing My Two Tanks Together

    I'm happy with my fuel capacity, so an aftermarket larger tank that would displace my spare tire isn't something I'm interested in. I always have a 12 foot camper on and a small trailer packed with motorcycle, generators, fuel cans, spare trailer tire, propane tanks, bicycles, ect., no room for...

    What did you do with the spare tire? or did you put it in the bed?

    Thinking Of Plumbing My Two Tanks Together

    So I've been crawling all over my truck trying to fix any air intrusion leaks on my "86" 6.9 f350 dually 4 door. Today while laying under the truck looking at the Fuel Tank Selector Valve (FTSV) I had a thought. Why couldn't I stick a line into the bottom of the rear tank and run it level up to...

    Could Someone Explain How These Valve Stem Seals Are Supposed to work

    I didn't force it but it does feel like it's sized to snap into the bottom of the retainer, but what good would that do? it's an inch and a half away from where the sealing needs to be. The old ones, shown in the pic were not snapped into the retainer, although they were all riding high up the...

    Could Someone Explain How These Valve Stem Seals Are Supposed to work

    I just received new stem seals for my 6.9 idi. I'm confused, the intake (not shown) look like the originals but the exhaust are way different. Will these work? how do they work? The picture shows the old brown one and the new white nylon one. Is this just a short version of the old one? it...

    Will The Valves Really Drop Into The Cylinder While replacing the Seals?

    So I've been chasing a really bad smoke problem on startup, Injectors checked out so I moved on to replacing the valve stem seals. I read a lot about doing the job, It sounded harder than it actually was, I just made my own spring compressor and it worked great no issues getting to any of them...

    Would This Be A Good Engine For A Rebuild Project?

    Thanks guys, I'm learning a lot. When he has the engine out I'll go take a look at it. My main concern would be a cracked block. Will it be easy to see a crack around the heater area or is there maybe a trick to make it stand out and easier to see?. I'm waiting for a call back from my...

    Would This Be A Good Engine For A Rebuild Project?

    Thanks, hoping for info on how to tell a newer improved block from an older problem prone block. I know it's very close to the change over.
