Fuel filter replacement Farm Pro2430

A lot of “old school” types will tell you to pre-fill the filter before screwing it on. I can tell you that at Caterpillar that is a BIG no-no! The reasoning is that you can get unclean fuel into the clean side without passing through the filter. On modern high precision systems it can cause damage. The proper procedure is to clean the area before removal of the old filter. Then clean the area again. Finally remove the protective film from the new filter only immediately prior to screwing it on. Use the primer system to get fuel through the filter. This makes sense to me although in all probability our “less precise” fuel systems are probably fine the other way, but why introduce dirt if you can avoid it.

I’m not sure on your Injector pump but on mine there is a bleed screw that has a ring through it. After a filter change, you loosen that screw and use the hand pump. This will pull fuel from the tank and push it up to the filter, filling it and expelling air towards the injector pump. Once you see a steady stream of fuel (no bubbles of air) you know the filter is full and there is fuel all the way to the IP. It should start and run normally, although there is a small possibility of tiny air bubbles causing to stumble for a few seconds as they get purged out.

It would be a really rare circumstance that you would need to bleed at the injectors, but that is doable it it won’t start.

Don’t forget to close off the bleed screw and tighten down the hand pump!

As a side note, when I assembled my tractor out of the crate I replaced the factory filter with one from NAPA after draining and flushing out the so called fuel that was in the system. (All fluids actually).  The tractor is now 15 years old and has 875 hours on it with the filter I installed during assembly. The replacement is on the shelf, clean and dry in the box, just in case I ever need one.

if it has chinese  writing on it is, if not it most likely been replaced at least once.

I was just thinking it might be a good idea to pour the old fuel into a jar just to see the condition of the fuel tank as if it is rusty it will end up in the filter. let it sit for a min. and look to see if it has any water also.

I have two chinese tractors a 2006 foton ft504a  and a 2005 le204a dong feng, those are both metal. yours could be different , I think the farmpro is  a jinma.
