We make custom fuel line kits to fit Holley dual feed carburetors in #6 and #8 line. They are made from absolutely the finest quality line and red and blue aircraft fittings, and come fully assembled including bowl fittings. Our line kits are also available with or without mounted AED fuel pressure gauges. Check our "Billet Components" page for our new Stainless and Braided line kits for our Billet Regulator brackets. Our braided line kits come attractively skin packaged for display.

We offer some of the finest gauges available today at great pricing! We have expanded our gauge line to include several models designed to give accurate readings and long life. New for 99’ are Liquid Filled gauges for additional shock resistance and optional pressure readings all the way to 30 psi. All gauges are 1.5” in diameter, chrome plated stainless steel, shock resistant, and can also be mounted on AED Fuel Lines. Gauges feature an 1/8” NPT male fitting and our attractively skin packaged.

We saw a need for a quality Nitrous gauge that could be attached directly to your NOS bottle. Our new kit features a 0-1500lb gauge that inserts into our billet AN bottle connector. You simply install the fitting on your #4 bottle outlet fitting. Monitoring bottle pressure is a must for safe & maximum nitrous performance. Kit comes attractively skin packaged at a price you can't beat.

AED Carburetor Spacers offer many distinct advantages that are worth mentioning. Besides traditional tuning changes in plenum volume which can improve torque and power output, Birchwood is a great thermal barrier. By keeping fuel bowls cool you get a noticeable increase in fuel density, resulting in a better charge available for combustion. We have seen results on the dyno of up to 20 horsepower. We originally designed these spacers for racing but soon found out the benefits on street cars eliminating hot soak and vapor lock problems associated with high underhood temperatures. Todays fuels have significantly lower boiling points compounding these problems especially with aluminum manifolds. AED Birchwood Spacers are available in 1/2” and 1” heights for different configurations. They are coated with a special sealer to promote sealing and give a great look. We also have Carburetor Stud Kits for the ultimate in carburetor retention. These grade 8 black oxided allen head studs make installation a snap. Kits come complete with studs, AN washers, and jam nuts.

We offer four different popular fuel bowl fittings for different Holley bowl designs. For the cathedral or center pivot race bowls we offer #6 and #8 AN anodized and machined bowl fittings for braided fuel line. For Holley 600 or side pivot style bowls we provide a straight outlet and a banjo style fitting that swivels 360 degrees for extra air cleaner clearance. Both of these fittings accept 3/8 push on fuel line.

These are absolutely the finest linkage kits available for sideways carburetor mounting. All kits use aircraft quality components, including left and right hand Heim Joints for precise metering of opening and closing rates. There is virtually no flexing which translates into reduced pedal pressure and eliminates overcenter problems. All kits come complete with instructions and will work with virtually any carburetor and manifold combination.

These professional fuel logs are perfect for splitting the main fuel line to the regulators and keeping high pressure fuel on tap to the carburetors. This additional plenum chamber greatly reduces fuel system load and float drop. The AED fuel log is made of high quality black anodized aluminum with a 3/8 NPT inlet, 2 welded 3/8 pipe nipple outlets, and optional 1/8” NPT outlet for fuel pressure. Essential for Alcohol.

We offer custom stainless steel vent tubes that we machine on the lathe for more precise fit and durability. They are custom polished and available with angle top cut in three popular lengths. Great for adjusting heights for hood clearance and fuel spillover protection.

We make a Polished Stainless hard line kit for selected regulators that’s absolutely stunning. This high quality line kit comes complete with fitting for fuel pressure gauge where applicable. For engines not requiring a regulator we have a line kit that includes a #6 male inlet fitting for line hookup (see "New Products Section"). Our Stainless Line Kits also work with our New “Regulator Brackets” found under "Billet Components". Attractively skin packaged for display.
