Yes. Whitehouse doesn't take returns, so after I found the LH pump was the wrong one (for my B7100), I ordered a RH one and installed it. Works great.
The difference between the LH and RH pumps are the inlet/outlet are reversed. If you flip your RH pump upside down you will see how the WHP LH pump would mount (although the pipes cannot be connected of course. The inlet and outlet are different sizes).
Here are a series of images of the two WHP pumps. LH pump on the left, RH pump on the right:
If you are interested in my LH pump, send me a PM with your shipping address and I'll look up what that cost would be. I'd like to get 1/2 what I paid for the pump itself.
