I posted the following a day or two ago in my thread for my Case 444 (K321):

 

"If Niagara Falls is a fitting name for your fuel pump.....does it need to be rebuilt? frown1.gif I started the Case yesterday to move her around a bit and out poured fuel all over the floor. Upon closer inspection I noted that the seals were shot."

 

Tonight I rebuilt the fuel pump and here's what happened:

Any help you might be able to offer in the thread above would be appreciated. Thanks.

Even though I answered to your other post. I just wanted to add that I am a fan of rebuilding these old pumps. The biggest problem I have seen is the disks getting gummed up or something lodged in them holding them open. So if you have good diaphragms and gaskets I would rebuild it again (IMO)

It sounds like the pump is dead headed either internally or by an external blockage and is building pressure until the weakest part gives out. Personally, I'd try once more to find the problem and rebuild it then if that didn't work I'd go for a new one or an electric pump.
