Oliver 70 Missing Fuel Line and Parts - Please Help

RTR · Jul 18, 2019

I have an Oliver 70 row crop and the previous owner (who had dementia) removed the fuel line from the gas tank all the way to the carburetor. I ve had the tractor running well on a pony tank but I m ready to hook it up correctly. The original gas tank is clean so I m ready to buy parts and install.

Here is my issue ..... I have no idea what to buy to get it hooked up. As you can see in the pictures, there is a brass elbow screwed into the bottom of the tank and that is all I have between the and the carburetor. I know it should have a fuel sediment bowl somewhere but there isn t one on this tractor. I don t even know what type of size fittings I need. I m ready to order the correct parts and get it done. Please point me in the right direction.

I don't have any pictures of it,but I went to the hardware store and got a short length of 1/4 copper pipe and an elbow for the bottom of the tank to get out away from the bell housing then put a sediment bowl on that pipe,followed by copper tubing to the carb.

scootergmc · Jul 18, 2019

The sediment bowl usually mounts on the right side of the engine, just forward of the bellhousing. Here are just a couple videos for reference:

Yeah I had no idea about that. What size thread is that elbow in the tank and what all do I need to connect it all up ? The tractor is 100 miles away from me and I d like to get the parts before I leave town tomorrow night so I can fix this weekend.

Here's the way mine is. As far as I know factory set up was the same.

you have a picture?

Ken Loewenhagen · Jul 18, 2019

This is the way mine is. Almost like factory

Ken Loewenhagen · Jul 18, 2019

Had to try 4 times before it let me send a picture

Ken Loewenhagen · Jul 18, 2019

All male fittings are 1/8"pipe. You will need 1/4"copper tubing. Buy extra, it kinks easy. Starting
at the tank, if your threads are good on the tank fitting, you will need a nut and ferrule if not
you will need a 1/8" elbow for 1/4"tubing.I bought a new sediment bowl assy. It has external and
internal threads. If yours is like mine, you will need a straight fitting with 1/8"pipe thread with
a ferrule and nut for 1/4"tube. Screw the fitting inside the assy. You will need a 1/8" 90 elbow to
screw into the outlet fitting of the assy. It needs to be for 1/4"tube, then you will need a nut
and ferrule. Some places you can get this as a kit. On the carb end, you will need another 90 elbow
nut and ferrule. That should get fuel to the carb. You'll notice in my picture there's a bracket
that holds the assy to the side of the engine. My assy, threaded part, goes up through that
bracket. I took a 3/8"pipe coupler or union and sawed about 3/8" off and used that as a nut to hold
the assy in place. Anymore questions, let me know

Ken Loewenhagen · Jul 18, 2019

Forgot to ad if there are any of the original nuts left on a line somewhere, they take a 5/8" wrench, the new ones will take a 1/2" wrench.

Thank you!! I will try to get the parts tomorrow. Should be able to get everything up and running and use a rubber line section in place of the sediment bowl until that is ordered and comes in.

Have any idea who would have the original style/correct sediment bowl and the bracket that is needed?

Thanks!

The bracket you can make, that's simple. I could not find a new original style sediment bowl assy. I think the one I bought fit a M farmall. Don't remember if there were internal threads or not but you can put threads in it with a 1/8" pipe tap.

Please show a picture of the bracket with Dimensions if possible. Also the exact location it bolts to and how the sediment bowl fastens.

Ken Loewenhagen · Jul 19, 2019

I'm not near the tractor now but, it bolts to the lower rear corner of the engine side cover. It's
maybe 1-1/2 to 1-3/4" wide. Probably 3/16" thick. It drops about 1-1/2". Then it has a bend which
brings it out at 90 degrees with about a 45 degree bend to the front. This is all in one bend. You
will have to drill 2 holes. One for the bolt and one large enough just so the sediment bowl threads
go through it. I will try to get you a picture tomorrow morning. If you just need something
temporary to start and move the tractor, if the elbow is still on the carb, get a length of 5/16"
or 3/8" hose and 2 hose clamps. Slide the hose over the end of the fittings and clamp them. This
will let you run it for a while. If you need to shut off the fuel flow, you can pinch it off with a
vice grip. If you have anymore questions, please start a new post.

What is the larger round black piece? A rubber piece? How is the bowl assy secured to the bracket ?

Gary Mitchell · Jul 20, 2019

I bought an elbow, 2 barbs, a couple feet of black neoprene or "whatever it is" fuel line and an inline filter. ;-) gm

scootergmc · Jul 20, 2019

I wanted to help so I went out to take a photo last night as we have three 70s in various states of disrepair. One has a rubber hose tank to carb with an inline filter, another had a sediment bowl directly on the tank with a line going to the carb, and the other had nothing but a metal bracket different that what's been posted by Ken. Ha.

RTR · Jul 20, 2019

(quoted from post at 20:10:53 07/20/19) I have entered pictures below your last post

I see that I have the bracket. Not sure what the 2 holes are for though. They don t look big enough to mount a sediment bowl and not sure why there are 2 and not 1 hole.

RTR · Jul 20, 2019

My pictures of the bracket as described above.

scootergmc · Jul 20, 2019

That's the bracket we have on ours.

scootergmc · Jul 21, 2019

This is your factory setup. You just need the correct bowl assembly.

That makes sense now. I ll see if I can find one on eBay I guess. It looks like I m also going to be looking for a CLEAN gas tank. This one was apparently lined in the past and now it s all coming apart inside. I was pulling pieces out at every grab.

scootergmc · Jul 21, 2019

Well I stole that picture of eBay, so there's at least one on there! Ha. I'd just take the tank to a radiator shop and have them boil it out. After everything is said and done you'll be happy you did. I bit the bullet and did it with an old TD40 tank. Couldn't have turned out better and even the radiator shop was pleasantly surprised.

I could have it boiled out but I m afraid the tank is too rusty to be repaired. Something caused that old tank liner to start peeling and falling off inside that tank. Looking inside it is pretty rusty all over. [/code]
