How to crush your fuel regulator
I have 2 examples of fuel pumps and regulators to illustrate how to crush your fuel regulator for PERMANENT increased fuel pressure.04 ZX10 left/06 ZX10 right
This is a delicate proceedure and a small move goes a loonnnnggg way, so be gentle.
Remove the fuel pump, behind a small plastic side piece on the fuel pump body there will be small cap/cover.....GENTLY pry/unclip this cover to expose the regulator.
Next,pull out the valve, some gentle prying and twisting may be needed, as there is a very tight fitting O-Ring holding it in place.
Find appropriate sockets to support the valve body as shown and place in a vice........GENTLY apply the first nudge of pressure, moving the socket into the valve body just enough to make the metal flex....1/64" or less.
Fabricate an air chuck to hold the valve so you can apply air to see when the valve lifts to relieve pressure.
You can check before you crush, to verify that it's at 40psi or so.
Crush to desired PSI and re-assemble.
