Just a couple of thoughts,check with a welding or a machine shop and see if they could make up a steel or aluminium tank with a thicker flange to fit the pump.The other possibility,is having an adapter made up to go between your pump and a new style tank.Also,maybe the new style tank will bolt up to the old style pump without an adapter.

I realize that in most cases it's something simple like you guys are brainstorming. My brain is now 5 years into this and exhausted all of these possibilities. It really is a design flaw. I have come to learn that Lippert only made this pump for a few short seasons and got away from the design real quick. I have talked to many other rv'ers that have this model and have the same problem. Lippert and FR just ignore them and act like they've never heard of it.

I have taken it all apart several times. And have done a ton of investigating the last 5 years.

Looks like I am buying a new pump. Lippert Components RV Parts and Accessories|Hydraulic Slide and Leveling Components

Just wish Lippert or FR would help me out on it. Looks like I may have to start a new website & and start hosting all of the other rv'ers complaints as well as mine.

That pump in the link you posted which has the black flange connected to the white tank is the unit we have and it leaks around the flange...Thanks for all the info folks...Just started wrapping my head around this issue...AAARGh

I have some suggestions of people to contact or at least they may be able to steer you in the right direction
Baum Hydraulics Corp
FORCE America : Leading Innovator in Mobile Hydraulic Solutions

now with that being said ......
If these do not work out for you I may have a pump with mounted tank.
It was used for a wheel chair lift on a bus . I will take a few pics for you tomorrow .
It was and is in good working order .

I like the O-ring ideas. Fifteen years ago I worked for a hydraulic outfit and O-rings come in different thicknesses, diameters, material, and shapes. I like the quad ring idea. BTW - if anyone farms and has a yellow round baler that is 15 years old, I can guarantee I assembled the hydraulic valve package that operates the door and controls the twine tension on the bale. That was a drinking job, same thing every day.........
