Hydraulic hatch accuators
 

any ideas? Here's the deal
I have these hydraulic rams I plan to use to open and close my two hatches on the cat project. I also planned to use a trim pump to power these rams. The problem is the trim pump tank does not have enough capacity to fully open these long cylinders. Do they make a larger tank to fit the trim pumps (probably not) should I try to modify a tank to fit the trim pump that has enough capacity?

These are the tanks I have now.

I am also wondering if they make a larger tank. I have the same problem! The tank on my bennett pump dose not have enough capacity to fulley extend my rams.
