It ended up being the relief valve at the end of the fuel rail. Knocked it it around, back on and going again. Thanks again for the help

Thanks I didn’t know that and will get them corrected

I have never heard of that as I have installed them in this tractor about two years ago and it has been running fine until recently. As of yesterday it will not even start without a lot of cranking. It still runs perfectly until I load it. I have a Mechanic with the correct software coming to...

New injectors with very little flow back to tank. It still takes awhile to start. I have flow testers on each injector. One more question is how much fuel should be coming out of the filter back to the tank?

Have installed new injectors. No excessive fuel flow back to tank. running good once it starts but takes awhile. Next question How much fuel should be coming out of the fuel filter line return to tank?

I have new injectors. Just got to put them in, but it awful hot where i live

Only under load P0093 only Derate and warning light

Thank you. The tractor runs perfect with no codes until i get into heavy grass. It then losses power and shows p0093. I have no leaks and if i clear the code it will run fine until i load it again. I tried cutting the fuel valve off at the separator to let it run out of fuel and it did stop...

FYI I put a gauge on it and it is + or / 70 psi at idle. I’m still working on the p0093 code. I have found a small leak at the rail pressure sensor. It drips and when I raise the RPM it drips more . I’m hoping it’s just the o ring.

My problem is that I keep getting a red light and and low rail pressure code. Turn off tractor and back on and it runs fine until it gets loaded with the mower in tall grass. It will run fine if I don’t load it. New filters, clean system and new fuel. It starts immediately. I guess i’ll try a...

Does anyone know the pressure between the mechanical pump and the injector pump. And maybe an idea on the volume? It seems like there is little discussion on the mechanical pump.

It is a V1505 EF02

This is the engine that is in my KX71-3S and need a new one, so I defiantly want to get the right one. Any help would be appreciated.

Can I replace a Kubota V1505 -EF02 with a V1505 ES?

The engine is bogging down when warmed up and I try to operate the hydraulics. When engine is cold everything works perfect
