About feed pump

Hi,

Anybody there has one regulating valve spring (41-up) to tell me its free lenght?
Measured mine 51,5 mm. I suppose its 713-41, maybe wrong spring. Setup was 3/8" for screw.

Thanks,
JON

As coincidence would have it, I received by mail today a set of three ball bearings and the three springs to redo my feed pump. The regulating valve spring measures exactly 52.0 mm. The check valve springs measure 43.8 mm .

Thanks for info. Spring seems to be ok by every measure.
