On the base of the oil pump is a plug. I believe it takes an allen wrench to remove it. After you remove it, a spring will come out and then the relief valve will come out. The relief valve is a cylindrical shaped plunger and is hollow on the back side to allow the spring to go inside it. Anyway, find a round piece of metal about an 1/8" thick and the same inside diameter as the plunger, install it into the relief valve plunger, reinsert the spring, and reinstall the allen head plug. That should give you about 15 more psi.
