Thanks! I talked to Kevin. He said he didnt think the 550 diesel came with a lift pump, but the 6 cyl did. Suggested I take it off and let it gravity feed. I m pretty sure my pump is factory though. Either way, he said the lift pumps like that are no longer available. I guess I ll be trying my hand at a rebuild kit!

I don't know what your pump looks like but on my super 55 and on my 550 engine the pumps came apart really easy. Mine didn't leak into the oil but both had one check valve out of place. Make sure to set them in the proper direction and "stake" them to stay in place. Your tractor won't run right without the lift pump. BTDT.

Thanks guys. I ordered the rebuild kit. I thought about doing away with the mechanical pump and juast using an electric one but I want to keep it as original as possible. Ive been thinking of selling it to get something a little more parts freindly. But I LOVE this tractor so much!!!!!!!!1
