Hi, I've got a '53 Ford Jubilee with the original vane type hydraulic pump for the 3-point lift. I am having a problem with it settling & not lifting once the hyd. fluid is warm. It works fine when it's cold so I'm assuming it's probably wore. I was wondering if anybody has used "Lucas Hydraulic Oil Booster & Stop Leak" added to hyd. fluid? They claim it will boost pressure on worn pumps & I thought it might be worth a try as it's almost impossible to find a good used vein pump & I really don't want to spend $700-$800 on a piston pump conversion. Any thoughts on this would be appreciated.
