I have an International 464 diesel with the D179 engine.

I have been working on changing the fuel filters and am ready to tear my hair out (the little that is left).

The filters are the cartridge type with glass sediment bowl at the bottom.

Here is the problem. Primary filter went on, fills, and bleeds the air out OK.

The secondary filter has flow to it (from the primary), but the filter and bowl won't fill with fuel. The vent screw for this side has ample flow, but the filter and bowl will not fill.

Any ideas on what I am missing or a fix?

Do you have a fuel pump with a bleeding plunger on it? I don't remember if the 3 cylinders had fuel pumps.

Try these if you don't:
Check the flow from the fuel tank and also check the flow from the fuel tank cross over tube.
Try adding more fuel to your tank if it isn't already full.
Try cranking the engine over to have the injector pump pull the fuel through.
Buy a vacuum-type brake bleeding kit and suck the fuel through.
Pressurize the fuel tank by hose-clamping a piece of inner tube over the filler neck and poking a small hole through it. Then SLOWLY add compressed air to the tank and have somebody watch the filter to see if it fills.

So I got it to fire, it will run for 20-30 seconds, then sounds like it is starving for fuel. I believe the filter is full now.

Does anyone know if this tractor does have a fuel pump?

If you do have a fuel pump it will be attached to the right hand side of the block. It bolts to cover #15 and goes in the place of cover #42. If it's not there then your fuel injection pump acts as fuel pump.

Sounds like your system still has air in it. Try bleeding the lines that go to the injectors.
