Thank you a lot for doing this testing. This helped me decide that I will stick to the stock top since it's not worth the expense (the pump will be used in a mosfets/chipset loop only so it's not a biggie with about 1.27 GPM from the estimator including the SF800).

To get the benefit of a aftermarket top while being able to tube in a restricted height situation, I would need to get a aftermarket top with top inlet and a good elbow.
