One Way Valves, Non Return, Breather Valves &, Check Valves

Speedflow has a wide range of valves to help control with non return and fuel tank breathing. We have in line AN check valve (or non return valves) in -6 AN and -8 AN. We have the same valves but with 12mm x 1.5mm male at one end to fit the exit side of Bosch fuel pumps. There are a number of fuel tank breather valves, all doing the same job but they each fit differently and have slightly different capacities. Last of all we have the Speedflow manual pressure relief valve.
