Why is there not a filter between the tank and the fuel pump?

Would not start and the fuel pump sounded different. So, pulled the fuel line off the carb and sure enough, it wasnt pumping anything. Had to remove the body, remove the fuel tank to get to the line and pump. FINALLY got to the pump and got it off. I sprayed into both side of it with seafoam penetrating lubricant. Now, not sure what to do with it, lol.

Also, does anyone know the part number for the fuel pump on the 400?

You can go to JDParts.com and look up the part by doing a model number search. I just did that and the part No. has been changed a couple of times. The current part no. is AH130127. If you are registered with a dealer you can get pricing as well. The price came up as 101$ but I am in Canada so it will be different in the USA. I would think that any 12v low pressure pump would work on that. You might want to check with our sponsors to see if they can supply you a used one for less$.

Thanks for that. Is there any way to clear a blockage in one?

Good deal. But be sure the diaphragm doesn't leak back to the vacuum line. If it does, it can fill your block with fuel. If you lightly suck on the vacuum side, it should hold your tongue. If it leaks off, then it has a pinhole.
