I was really surprised by this setup. I was a little uneasy about ordering it because I wasn't sure if it was going to truly be able to replace the pump that came on my dump trailer originally but let me tell you, hands down you are getting your money's worth here. I have a 16' trailer with 4 foot walls with the dual piston and it lifted 5 tons pretty damn easy. I'm still not trying to shovel loads like I did sometimes with my last pump but so far about ten loads in I'm more impressed each time. As far as the fittings, yea they need to send the correct ones, I had hell finding them and not just any store stocks them. My local hydraulic store after about an hr or scrambling ended up finding what I was describing. I will say though this one is alot slower than my last pump and smaller looking but All in all I would order again. Good luck with the fittingsPs. The picture I put up is of one of the smaller loads, it's the only one I have.
