Two Twenty fuel

Hello,

My new to me 220 stops after a time driving with a decrease in engine speed and power finally it shuts off.
After waiting a time, it wil start again. I changed the filter, fuelpump is gone trough proffesional.
Could it be, that there isn’t enough fuel in the tank? Most times when I notice it, there is not much fuel left. But it should be enough in my opinion.
Is it normal with this tractors, without fuel feed pump, to have a minimum amount of fuel in the tank always?

Thanks.

Return line on tractor is still plugged possibly. 

Well then, disconnect that line before the hand primer and it should flow more than a gallon in five minutes. 

Sounds a lot like the problem I had with mine shortly after a complete rebuild of the engine and pump. It would sit and idle fine, but once I put it under a load, sooner or later it would start to loose power and eventually die for lack of fuel. Once it dies, try to pump the primer pump. Mine felt real stiff like it had a vacuum on it. Come to find out, I believe there is a check valve in that primer pump. I bought either a new primer pump or a repair kit for it and haven't had that problem since, going on 5 years. Good luck, let us know what you find.

But if the flow isn't coming from the tank, the problem isn't the check valves. Start with supply flow FIRST.

on one of our 220's you could blow back into the tank all you wanted, but when the fuel started flowing so would the sediment which immediately plugged the outlet. Had to take the tank off and clean it out.

Debris likes to collect in elbow fittings in the system. Agree w/DR, blowing back to tank just means you'll deal with it again in an hour, a day, a week? But it will come back when you don't want issues lol!

Sounds like tank is dirty and plugging. You can try power washing or take it to a radiator shop. Tank has 2 baffles. Had my tank cleaned and then plowed for 40 acres to get clean. I like sediment bowl before primer and filter. You can see the stuff it collected. Is your fuel tank in a vacuum? When I unscrew my cap it pulls air in. Don't know why it does this! It will stop fuel flowing. I have to uncap it a few times a day.

A little less flow when it goes thru the hand primer by gravity, but you've got to have GOOD flow up to it first.

I would agree, except he claims the injection pump has just been gone thru by a professional. You would expect a pro to have replaced that flex ring, wouldn't you ??

Tried to drive it today, about half an our not a problem. But than it stopped again. Checked the check valve… dirty again. So i drained the tank and go clean it. Any tips to clean on the tractor? Because it is repainted I hope i don’t need to remove the tank. Thanks!

Cleaned the tank out as good as possible. Looks clean now.
Going to add a sediment bowl like it needs to have original before the primer pump.
I think the problem will be solved then. I have a small glass on it, like on a WD. Thinkt that would be ok, or does it neet one with a big glass like a d17 / U? The inlet and outlet looks the same thickness.
