Choose this part if the priming bulb is the part you need to replace and the rest of your siphon still fits your tank. The listing identifies the large FK018 version. Compare the replacement with your existing bulb, including the inlet direction and the hose connection.
The listing names 0.31- and 0.43-inch hose inside diameters. Compare the actual hose end and the corresponding connector before ordering. The maker's listing also advises keeping the valve orientation when reassembling the bulb after rinsing.
