Which oil pump spring to use?

[Tim Cucci]

I am rebuilding engine. I bought a Dynagear oil pump kit from Cotton Perf. The kit has 4 springs for different pressures. The yellow spring is the closest match to the original spring and is rated at 40 psi. Anybody used this kit ? Which spring?
Thanks
Tim

I did mine with a Mellon kit and the yellow spring also looked the closest to what I pulled out. It said it was a 60lb. I asked and most said that should be good.

Use the 60lb spring

Get the adjustable setup from T/A Performance and you won't ever have to worry about changing springs or what spring to use...
