Literally,

My 970 (diesel) has developed a small problem. It seems to be sucking air into the fuel line somewhere. Both filters were changed, thought they were plugged, maybe 50 hours on them. But I still was stalling out after about an hour. Not every hour but would happen two or three times in a row then go for 3 or 4 hours. Noticed that the filters had a lot of air in them when changed. So I checked and sure enough bout 20 cranks on the hand pump and I am running again. So all day, when it fails, I stop, remove bleed screw and manually pump it back full of fuel and go on. I suspect the line from the tank to the hand pump, hand pump itself, or steel line to the fuel pump, or fuel pump itself. Yes there is a half tank of diesel in it. Everything after that I would think should be leaking out and not in. But I am not loosing fuel when shut off. Augggg....

So what do ya think would be a good way to find it?

Remove feed line at pump an if not a full stream of fuel you probably have a clogged pencil filter that is located in bottom of fuel tank. it sticks up in tank an you need to remove line at bottom of tank to get it out. It is messy an you need to be very careful an not turn fitting loose on tank part or it may leak. Quick fix is to put air pressure on line an blow dirt off filter (open filler cap first) That was trouble on my 1070. Some where in book is mpshows filter.

Had the same problem on my 1030 ck replaced the priming pump also make sure there is no trash in the check valves on the priming pump. they will suck air thru a bad priming pump.my 1030 got so bad it would omly run about 20 min. between bleedings runs fine now

You might have trash at the 45 degree elbow that nylon line from tank hooks to at sediment bowl. Remove elbow and sediment bowl\screen to check.

I found on a 870 it had a nylon screen on the fuel line in the bottom of the fuel tank. On this one the fuel jelled and wouldn"t run. It could have some junk built up on it. It is on the elbow in the fuel tank.If you had air leaking into the incoming fuel line you would leak fuel when shut off.

There is a better chance that you have an obstruction in the line. Check the priming pump check valves for junk, and elbows and fittings. If you remove the fuel line at the priming pump you should get a full stream of fuel running out gravity flow. Good Luck DK

Hi Walt has a good suggestion there. You could take it one step further and spray some liquid soap around the fittings. The air will cause it to bubble up. Just a thought. Good Luck Lester

Hmmm, I run 2 970's on my farm and haven't had that problem. If you have a hole in a line or a bad o-ring on the hand pump you should being seeing fuel leaking out when off and air when its running(as you stated). I have had the problem of somthing in the fuel tank that plugs up the line....when it stalls the suction is gone and the debri (leaves, chaff, bug) floats up in the fuel again. If you can your fuel to your tractor I would say this is a difinite possibility. Somtimes it can be somthing simple that causes you the most problems....Hope ya figure it out.

Remove line from tank then add about 10 to 20 lbs air pressure to the loose end. Watch for bubbles all along the system.
