Army Navy Fuel Line

One thing that all race cars share is the fuel plumbing system. Army Navy fittings or commonly known as AN Lines are anodized aluminum fittings used with braided stainless rubber hose. There are a few reasons to use this system: 1) They are more durable than standard rubber fuel line and barb fittings. 2) The connections are easily disconnected and reconnected with out damaging the hose, like with the barb fittings and hose clamps. 3) Race tracks only allow a few inches of rubber hose in the entire fuel system. 4) It looks damn good.

 The carb is a Holley 750 cfm street avenger with blue fuel blocks to match the theme in the engine bay. The carb comes with rubber fuel lines as a kit to get you down the road, but it looks a bit ghetto and not too safe in the long run. Pretty much they give you about six pieces of hose, connectors, and simple hose clamps (The non screw on type). The kit used above is Part#641090 from Russell Performance, it comes with a pressure gauge. We also had to purchase a -6AN fuel filter, -6AN 45 degree fittings, and a fuel pump fitting, and about 3 feet of -6 hose. The lines really clean up the fuel system and give the race car look to the top of the engine.
