{"product_id":"holley-main-jet-extension-122-5000","title":"Holley Main Jet Extension - 122-5000","description":"An improved jet extension design that actually screws into the metering block. The main metering jet then threads into the end of the extension. The installation effectively moves the fuel entry point for the main jet out into the fuel bowl. In this location it cannot be uncovered by fuel, causing a lean condition, during periods of hard acceleration or braking. 2\/Pkg.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eImproved Design\u003c\/li\u003e\n\u003cli\u003e2 Per Package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Main Jet Extension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtension Inside Diameter:\u003c\/strong\u003e 0.136 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtension Length:\u003c\/strong\u003e 0.710 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtension Material:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Carburetor Metering Jet Extension Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Main Jet Extension\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eRequires the use of special \"notched\" float to achieve proper clearance and to operate properly.
