That looks exactly like the pump I used for my A14 ... brings back memories! It worked very well up front near the engine; never had any problems. The most power I had was when using a Weber/Ford carb (6,000 rpm engine), so it wasn't needing a lot of flow.

It is a lot better than the stock pump. I had two go out on me, and finally I said "never again". Plus I could use it pump gas into a gas can if needed

I used the little rubber grommets to mount it on the firewall otherwise the thumping noise it made would carry into the car.
