It controls fuel pressure. You can get it from cummins but it's expensive there. You can get them from some of our vendors here.

Cummins prices on the OFV just came down some so it is worth a check there. The OFV sets the internal operating or "feed" pressure inside the inj pump. If it gets weak this pressure decreases and decreases feed to the injection pump pistons.

I highly caution anyone against stretching the spring without a fuel pressure gauge. Anything over 45psi has the potential of blowing internal injection pump seals ($$$) splitting open the fuel filter and lines.
