Regulators need to be mounted as close as possible to the carburetor to counter the effects of G-Forces stalling fuel in the lines.  We have designed this kit to mount a fuel pressure regulator close to the carburetor and simplify plumbing the dual inlets.

Please measure your available clearance to your valve cover before purchasing, regulator & gauge plus bracket extends out approximately 6" from carburetor.

Please ask if you are unsure of your application.
