Pull out the high pressure fitting and it will have a funky fitting/ orifice looking piece. You can increase vol ume by simply drilling out these holes, but DONT MAKE THE TOO BIG or you will ruin it.to increase pressure you can either find a tougher spring, or add a few shims under one end, but again, more is not always better,as it could cause all kinds of failures,pump shaft, relief valve body,pump housing, hoses, and even kill your engine when something is applied.
