stronger800 Posted November 28, 2025 Posted November 28, 2025 I’ve never had one stick, or just stop pumping, other than I had a fuel tank cap fail to vent once and it starved the pump and sucked the filters dry; then something in the pump stuck in the starved position. I called my pump guy right from the field and he said “tap on it”. All I had was my pocket knife, hit it once, fuel shot out and it fired 1 1 Quote
CIHTECH Posted November 28, 2025 Posted November 28, 2025 If you have removed top cover and metering valve is free, quite likely you have a stuck delivery valve. Delivery valve is pretty far in. For the guys that can wait a day or 5, we recommend using Viscosity's Fuel System cleaner, we've had better results with it than Stanadyne for targeting a problem. 1 1 Quote

So do you add that to the pump when the top is open? Do you just simply pour it in the fuel tank and wait? whats the procedure? BTW i always use Stanadyne and when i opened up the top of the pump it was perfectly clean inside. 1 Quote
lorenzo Posted January 7 Author Posted January 7 Well today was the day, record high of 67 degrees and the ol gal is back up and running. Not trying to start a fuel additive argument so just remember im just stating what i did . Tractor sat too long between usage, wouldn't start and had no fuel coming from the injector pump. At the advice of a company in Iowa that rebuilds these style pumps the thought was to remove the top cap and pour in some Stanadine, let it sit and try it after a couple weeks so thats what i did. Today was warm so i tried it and it started. 23 Quote

hagan Posted January 8 Posted January 8 My 560 finally started a few years ago after we pulled it a couple miles behind the pickup and i had to think it had air in it and finally we got it bled out. But bought a old 806 a few years ago from a guy who put a bunch of starting fulid thru it and i got a used pump from a salvage yard and it ran fine 1 Quote

Our local diesel shop always told us to use Stanadyne so we always have. Glad to hear it is running again. 1 Quote
mader656 Posted January 8 Posted January 8 Now. Take it for coffee (or a drive) on the 5th of every month so it gets used monthly. 3 1 Quote

I drove it around for two hours and then one of my sisters showed up and she drove it around another half hour then i let it run while i gave it a good bath. It got filled with fresh diesel and another bottle of magic potion. 6 Quote
DT Fan Posted January 9 Posted January 9 I put Standyne fuel conditioner in all my diesel fuel. Put it right in the barrel before they filled it last time. Never seen the stuff with the purple label. 2 Quote

Whoever inherits it probably wouldn’t get it to that point, they’d take the shifter to the knee and be laid up for a few days. 🫣🤣 1 Quote
