7060 fuel issues

7060 black belly. Was using to rake hay, shut it off for a few minutes and wouldn’t restart. Couple hours later I was able to get it started and back home - seemed to be getting air in the system, well then the primer pump was leaking - so guys at Spencer diesel said instead of replacing it to put electric one on from Agco- did that, worked for a week. Yesterday I went to start it and it wouldn’t fire - smoke but not enough to get it going - gave a small shot of ether and it’s off and running. Pulled it up by the shop and rechecked my connections- this morning same deal- crank with smoke, give it a sniff of ether and it’s off and running great. It’s 80 out. Do I have a touch of air in it yet, or pump on the way out? Once running it runs great. Numerous posts mention the return line being plugged could cause issues - is this just the line on top of the injectors? Changed filter when I did the electric pump.

Where did you locate your pump? I didn’t have any instructions so I basically replaced the primer pump - so it’s drawing from the filter to the injection pump - wondering if I should mount it by the tank and push as opposed to sucking more.

I did pull the return line off - it is clear.

That is to high I mount them down near the tank back of the batts on the strap I think it for lower shield You can call me 717-354-4736 I put on 12 

I think Doc has a great point. I have had similar issues on 2 different tractors (not AC) and the end result was a plugged strainer inside the fuel tank on both tractors. I also had issue with the fuel line rubbing the block and the vibration caused a small hole in the line allowing air to get in the fuel.

Replace the rubber fuel lines BTDT on a 7080 and 7060 they have micro cracks and are letting air in.

Pretty sure the electric pump was first used when they added a second (water separator) filter. They must have felt the injection pump needed some help when there were two filters instead of one.

I had an N-5 combine one time that ran fine, got shut off for lunch and would not restart. The delivery valve retaining nut had loosened up. Never had another pump do that. How many hrs on your pump?? 5,000 ??

Fried of mine has a 220 that would not start. Turned uot that the mechanism in the pump that turns fuel on or off is spring loaded in the direction that turns fuel on. When you push the fuel knob in to shut off the tractir it is positive action but when you pull it out to start it a spring pulls it on. It had gotten stiff and wouldnt go to run. We sprayedit with penetrating oil and worked it by hand untill it flipped back like it is supposed to. Tractor fired right up. I dont know if a 7060 is like that or not
May or may nit help

Sounds like the metering valve is sticking, try running a good fuel cleaner through it, then gently rev it up and slow it down repeatedly, to work it back and forth. You may need to take top cover off pump to clean it up better if that doesn't work. All this is just buying time until you can pull it off and get it properly rebuilt. I was thinking the Delivery valve stop screw backed out like Dr mentioned, but shutting it off and pulling the shut off knob out right away while the metering valve is still moving sort of smoothly, and it'll start tells me that's the problem. I have this hot shots diesel flush that can help clean gummy stuff like this up, you take off the filter, and fill it with this stuff. Maybe you can find it locally, as I don't ship that stuff lol!
