High frustration level today. Sometimes the effort to keep a tractor original is just not worth the trouble. Can anyone tell me why, when I screw the compression fitting into the sediment bowl, the gas line just pulls right out the back of the fitting when I am done? Can't possible be a good seal there! Don't want to put a bunch of gas in it (again) and have it drip out then have to drain it to fix it. Headed over to e-bay to see if I can find that rubber gas line again. Looks like the trip to the bone yard was a waste.

Did you get the OEM-style nut/ferrule from IH?

If you used a common style nut and ferrule from an auto parts store, the ferrule will be wider, keeping the nut farther out, so it engages wth LESS threads than is you used the CORRECT part.

I used the 5/16 brake line, new sediment bowl assembly and it works like new. You can buy the fittings from TM tractor supply.if your sediment bowl is in good shape the compression fitting will work.

But it is always best to shut the fuel off if it is going to set for a while.

Dear Dave, There may be one or two issues now. One may be that the threads in the sediment bowl are bad, limiting the seating of the fitting.
The second is the use of a new brass compression ferule (the little brass ring that is put on the line after the threaded part is slid down a ways. This compression ferule is available at hard ware stores. If it has been compressed, and abused to remove it, it will need to be replaced. This may be frustrating, but (though "educational") it will be correct. JimN Still believing

Hi Jim. I pulled the sediment bowl assembly and brought it in here to the office where I have a big-a magnifier. I would say the chances of anything seating inside that messed up thing are slimmer than none. I don't know how they got it to seal before 'cause I know I didn't do that to it. Unless Rusty has a solution I am thinking I will order a new assembly and a new fangled rubber hose gas line. There comes a time when it is just better to shoot the horse and put him out of his misery. Meanwhile I better push the 2N inside and start tearing off the sheet metal or I will run out of summer before I get these tractors going.

I will say the following: Don't use a rubber hose on a gravity system fuel tank. (or copper for that matter) The issue is fire safety. Putting a sediment bowl on it from a different source will work, NAPA has them and it only needs an elbow to be ready for flow. (the standard 5/16 comperssion fittings will fit that)! JimN

Been sitting here stewing about this. I came to the conclusion that the compression fittings MUST work if all else is correct....so I am staying the course and will get some brake line. I'll go into NAPA and see what kind of options they have to replace the sediment bowl. What sort of "elbow" are we talking about here, though? Something like what is on the carb only without the screen? Leave me a note if you will, I have a pretty nasty situation here and only came in and checked the postings to calm myself down. Just went out to close up the chickens and found the family dog on the brink of death for no reason.

Sorry about the Health of your dog, they get into things sometimes that get them seriously ill with hard to determine causes. They often do not show much illness until they won't get up. Best of luck, and may it be simple. Most of the universal sediment bowls have a straight in, and straight out 1/8" pipe thread. Thus A regular (male on both ends) Elbo is needed to hug the bottom of the tank. JimN

Dave,
Once the "olive" is compressed on the line, that will seal and hold it in. I got my line and fittings at the local TSC store. You may also need a tube bender as you don't want any kinks in the line.
I bet Rusty can help you out.

Paul

From your lips to his ears....you have NO idea how badly I want to try out my rebuilt carb. Naw, that's probably not true at all...you probably DO know how badly!

Dave,
Use a piece of 5/16 OD steel brakeline. Your auto parts store will have the correct fittings as well. For less than $15 it will be just like new.

Thanks Paul, but I have been to no less than nine auto parts stores, two plumbing supply houses, and the "old-timey" hardware that sells everything and have been told by each and every one of these that nobody will have a male fitting of that size. I did not believe it, but was true.
Anyhow, got the fittings at the bone yard along with a used gas line with the same coppery finish as the original EXCEPT this one turned out really was copper so I had to scrap it for the fittings.
Just really don't have it in me to go buy brake line on spec because I don't see how it would work any differently than the original 5/16 steel line I am trying to install now. Won't the brake line pull out the end of the fitting too? If not I sure would like to know how that works. Sorry to sound so frustrated but I have about ten days of waiting and a lot of money into something that seems like it should be so simple.

I had trouble finding the 5/16'' fittings when I needed them, too. What I found was that most auto parts stores had a spot for them in a bin or tray, but that it had been empty for some time and it was ''too much trouble to re-order them because nobody needs those any more, those were for OLD CARS.'' Special order only.

I finally found an Auto-Zone where the manager took great pride in staying caught up on her inventory, and SHE had them in stock. I could have hugged her (tall good-looking blonde, too).

As for your replacement line not fitting, I had a similar problem with a Tisco fuel line. It simply isn't formed correctly. You can easily see the mistakes they made if you compare it to the drawing in the parts book. If yours is a Tisco line from the same production run, this is likely your problem, also.

I needed to get the tractor running again (you have to run them to keep them running), and finally went with a neoprene line that was SPECIFICALLY DESIGNED for fuel delivery. I routed it very carefully to keep it away from the exhaust manifold.

But that's a short-term solution. The long term one is to buy and bend some steel line myself. I've done a little metal working before: but unfortunately it was mostly metal buildings and radio chassis and cabinets, not brake or air lines.

As a result I have ruined several lenghts of line but have yet to produce a fuel line that fits right and looks good. When I finally do, the neoprene one comes off.

If you can find a v pulley where the v goes to the bottom, you can make some nice bends without kinking the line. Also I think you have to get the small brass rings from IH because they are different than standard hardware fittings.
