Pump is a decent value as it’s a little more than the price of just the gaskets.

I have learned the hard way that these pumps do not have a weep hole. A weep hole is extremely important in any installation where the fuel pump is lower than the impulse port. Without a weep hole fuel and oil will build up in the pump and cause it to hydrolock and stop pumping fuel. Pumps from Leading Edge Airfoils do have a weep hole. FYI!
