JD 210c help

I tried to start this hoe today to keep the battery up. It would not fire which is abnormal for this machine. Long story short, I got it to fire by bleeding at the injectors.

After getting it running I noticed bubbles coming up from the inlet in the fuel filter. I tried a differnet filter thinking the o rings may be worn. No bueno. I have an air leak somewhere.

I tried bleeding it at the filter using the prime pump on the side of the block and along with fuel I get a lot of air. There is over 1/2 tank of fuel in the machine.

Does anyone know of a way to find where the air is coming from without replacing everything back to the tank?

Thanks.

Just check your fuel lines. They do tend to crack over time and suck air.

Very good possibility the line is original. This is the only soft line from the tank so its probably my issue.

Is there any way air could be sneaking in at the primer pump?

 

[CalTreeEquip]

I suppose its possible but I have never seen it. Bad fuel lines or loose connectors happens all the time.

Good deal. Thanks for your help. I did check all the compression fittings. I will replace the fuel line and go from there.

Other than some hydro lines this machine has been pretty dang skippy.

I got this machine running today. I had a new fuel line made and installed it.

As I was trying to purge the filter I could hear it sucking from inside the tank. The top of the in tank screen was above the fuel level.

Apparenlty the loswer portion of this screen is clogged. I put enough fuel in the tank to cover the screen and all is well. Its a tad perplexing because I completely drained the tank and cleaned this screen last summer.

Taking the screen out of the tank is a royal pain in the rear. Are there any options for some type of inline fuel screen?

I'm sure you can install a inline filter.
It maybe that the filter screen fell off the suction tube. Maybe probe around the tank with a magnet, see what you catch.

The filter screen is definately connected to the outlet. I may try to fab an inline screen maybe with some large Id pipe and some fittings.

I'll tell you what I've done in the past...

I took a compressor and had someone put the hose/nozzle in the fuel tank inlet, stuff rags tight around the nozzle so you can put a FEW pounds air pressure in the fuel tank. Then I go look for fuel leaks, as if it's sucking air, it will probably leak in that spot...

Works good to bleed air out of the system to the injection pump too. (as in filter changes)
