Injector pump gasket

[Backdraft]

I have a Case 580SE (2wd). Farm use, Motor runs great. The injector pump gasket has a bad leaking arond the top. I have removed the top (very carfully). Did not remove pump. Cleaned top and base very well and use a blue gasket sealer (rated for Diesel fuel). Placed spring back as i found it. Let dry a couple days befor introducing fuel. Runs great, leakes even more. I did not use a gasket just sealer. Should I use one or just use a better sealer? What type?

Thanks in advance

There's a bit of pressure there, so A) I would use a gasket, and B) check your fuel outlet fitting/check valve, and tank return line system to be sure there's no restriction causing higher than normal pressure inside the pump. But that's just me, perhaps more experienced hands will chime in.

What he said plus, make sure that the cover was not warped by someone trying to stop a leak by over tightening fasteners.

Hey TPG, so that's the trick? Two gaskets, hmmm, great idea!

You dont stackem them like pancakes? Sealer/gasket/sealer/gasket/sealer

Thanks, Lots of great info. I will give it another go. After I get this fixed. I need to rebuild the suttle shift tranmission. Oh what fun that will be.

Looks like gold in the bottom of the pan, I'm rich, Crap its parts of the transmission

Problem with using sealer with gaskets, especially with two stacked is the sealer could act as a lubricant and cause them to slip out of place

Have you tried that with rubber valve cover gaskets? Did that once many years ago. Thought the engine had exploded under the hood of that R model Mack!

Be Smart and do exactly what thepumpguysc says, I'll add to it to make damn sure that all areas are extremely clean and you might as well get the rubber O-Rings that go in the throttle shaft and fuel shut off shaft because they will leak next. You can get those gaskets and 4 rubber O-rings as a kit.
