I have had a check valve in the injection pump stick on a couple of my tractors that don't get used a lot. If you disconnect the line that goes from the fuel filter to the back of the injection pump and you have fuel to that point, it could be that check valve. With that line disconnected, you can push a small screwdriver gently in the back of the pump to free up the check valve.

Here is my newest and one my favorites. It is the 1/16 precision 1460 that Ertl came out with last year. It is a really nice model.

Thank you very much for that information. I will use the cap I got from the dealer.

I got a new radiator cap for our 8930 Magnum from our Case IH dealer. It is the cap for the actual radiator not the deaeration tank. I looked up the part number (253858A1) from the Case IH website and ordered it from the dealer. The new cap that I got from the dealer is the part number I ordered but it is just a sealed cap with no springs. The old radiator cap has springs on it and says 15 psi. The old cap is what was on the radiator when I bought the tractor 10 years ago. I believe the purpose of the deaeration tank is to keep air out of the radiator by keeping it full and I thought the springs in the radiator cap regulated that. Can anyone tell me if the new cap without the springs will work correctly?
