I just installed a new electric/hydraulic pump on my dump. The unit is the ssame size of the old one. my problems are hydro fluid comes out of the vent when the dump is coming down, when the dump is all the way up it won't come down with pulling on the dump body, when going up towards the end, it sounds like it is out of hydo fluid. I called the manufacturer and when over all the hook ups with them. Everything is hooked up correct and they said it should work. I'm stuck and not sure what route to go. Any help will be greatly appreciated. Thanks guys.
