Blue spring upgrade.
Sorry if this sounds dumb but, I am new diesel trucks and the 6.0. I have heard of some doing the "blue spring upgrade." What is it and what does it do to improve fuel pressure?
Thanks

The new replacement "BLUE" spring is longer and
it holds the relief valve in place a higher pressure. It's a very easy update to
do.
