Welcome to eWillys.com, a website for vintage jeep enthusiasts. I update this website nearly every day with jeep deals, jeep history, interesting reader projects, jeep related info, and more.
These quick searches can help you find things on eBay. People list in the wrong categories all the time, so don't be surprised to see brochures in the parts area for example.
The links to posts below show jeeps grouped by models, condition, and other ways. Some of these jeeps are for sale and others have been sold. If you are unsure whether a vehicle is still for sale or not, email me at d [at] ewillys.com for more info.
There are plenty of interesting, unusual, historic and surprising stories related to Jeeps and their owners. In addition, some of these features have nothing to do with jeeps. This link will display all featured stories starting from the latest.
Looking for parts and not sure where to go? There are a variety of large and small new and used parts sellers both online and offline.
Importantly, the allure of buying a project jeep can be romantic. The reality of restoring a jeep can be quite different, expensive and overwhelming without the right tools and resources. So, tread carefully when purchasing a "project". If you have any concerns about buying a vintage jeep, or run across a scam, feel free to contact me for help, comments or concerns .

I have an original Hy-Lo pump on a 1964 CJ5 and need to get it rebuilt. Do you know anyone who can rebuild this?
Mark, that’s a good question. I have not heard of anyone rebuilding these. You might try adding a post to the the CJ-2A page. I imagine someone there ought to have an idea: https://www.thecj2apage.com/forums/

I have one of these on my 64 jeep. I had the jeep restored and the plow system doesn’t work.
The pump is full of oil. Any idea on why it is not working? I was in the process of working the air out
of the system.
I have a 1967 Power King Tractor that utilizes the large Square Model Jeep Hy-Lo Hydraulic pump to lift/lower the plow. It has a 1/4″ intake and output that connects to a dual action hydraulic cylinder. The unit is well suited for this operation. I have a manual hitch and wanted to make it hydraulic. I saw a Jeep Hi-Lo self contained unit UHT 37046. When it arrived I noted it was smaller,( almost square) had almost identical hardware and fitting on top except it only has one 1/4″ street elbow. How do I connect this unit to operate a dual action hydraulic cylinder? This tractor is my first experience with hydraulics so keep that in mind when you answer. Thanks, Dan
Hi Dan,
That’s a question that I can’t answer. Maybe a reader can? I can post it on the site for a response. You might also try these guys, as they might know something, too: https://www.yesterdaystractors.com

I have a model B on a 1966 IH 1100a. Do you have any information on this pump? Diagrams, GPM, etc.
Hi jay,
I am sorry, but I don’t have any other information than what is here (at least that I can remember). I did find this page, but doubt it is useful: https://www.farmjeep.com/farm-jeep-parts/implements/hydraulic-pumps/
You might try contacting Barry Thomas at Farm Jeep.com https://www.farmjeep.com/farm-jeep-parts/implements/hydraulic-pumps/ .. he might have more information that he hasn’t posted.
Best of luck in your search,
– Dave
