Hello

I've just bought some parts for the fuel pump on my perkins 4.236 , and they mixed up the springs , so i got two little transfer pressure regulating spring that's 6mm in diameter instead of a 10.6mm in diameter ;Lucas CAV DPA, DPS and DP200 transfer pressure spring - Diesel Injection Pumps and the delivery is expensive so i was wondering if anyone here knew the other specs of this spring , so i might be able to find it else where like amazon or a spring place or something .

Thanks
