EVIL ENERGY Carburetor Fuel System Bundle with PTFE Line, Filter & Regulator

About this item

Running E85 through a carbureted engine? Standard fuel lines will fail you. Ethanol breaks down CPE rubber inner tubes, causing softening, particle shedding, and eventual leaks — while unregulated pump pressure floods your carburetor and tank contaminants clog precision jets. The EVIL ENERGY E85 Carburetor Fuel System Bundle solves all three problems: a 20FT PTFE-lined fuel hose kit (chemically inert to ethanol), a 10 micron inline fuel filter (stainless steel element, reusable), a 4.5-9 PSI adjustable regulator (with gauge), and two 6AN to 3/8" hardline compression adapters that bridge the PTFE hose to your vehicle's existing metal fuel lines. One bundle — a complete, filtered, E85-safe fuel path from tank to carb.

Key Features of the E85 Carburetor Fuel System Bundle

• PTFE-Lined Hose — The E85 Solution Standard Lines Cannot Provide: Standard nylon braided hose uses a CPE rubber inner tube that ethanol dissolves over time. This kit's PTFE (Teflon) inner liner is chemically inert — it will not degrade in E85, ethanol, gasoline, or diesel. Rated to 1500 PSI working pressure and -76°F to 446°F, this hose handles high-pressure, high-temperature applications that would destroy standard rubber lines.
• 10 Micron Fuel Filter — Protect Your Regulator and Carburetor: The stainless steel filter element captures contaminants as small as 10 microns before they reach the regulator's precision valve or the carburetor's jets. Aluminum housing withstands vibration and corrosion. Reusable design — clean the element every 5,000 miles or seasonally instead of replacing it. Includes 1/2", 3/8", and 5/16" barb adapters to match any fuel line size.
• Adjustable Regulator — Protect Your Carburetor from Over-Pressurization: Electric fuel pumps can output up to 14 PSI — far above what a carburetor float valve can seal against. The 4.5-9 PSI adjustable regulator steps that pressure down to a precise, carburetor-safe range (set it to 5-7 PSI for most applications). The included pressure gauge lets you monitor and fine-tune in real time. Anodized aluminum body resists corrosion from ethanol blends.
• 6AN to 3/8" Hardline Compression Adapters — Bridge Hose to Metal: Most vehicles route fuel through 3/8" metal hardlines along the frame. The two included compression adapters connect the 6AN PTFE hose ends directly to these existing metal lines — no cutting, flaring, or improvised rubber splice joints. Black anodized aluminum matches the rest of the system.
• Direct-Fit 6AN Compatibility Throughout: The regulator ships with 3/8" NPT to 6AN fittings. The PTFE fuel line kit's 6AN hose ends connect directly. The hardline adapters accept 6AN on one side. The entire system speaks 6AN — zero mismatched threads, zero extra adapter runs to the hardware store.
• Built for E85 Carbureted Builds — Street, Strip, and Everything Between: Whether you are running E85 in a classic muscle car, a hot rod, a race-prepped small block, or a carbureted swap project, this bundle covers the full fuel path: filtration, pressure regulation, E85-safe transport, and hardline connection. Not for EFI systems.

Why Choose the EVIL ENERGY E85 Carburetor Fuel System Bundle?

• Filtered Fuel Protects Precision Components: The 10 micron stainless steel filter element captures debris before it reaches the regulator valve and carburetor jets. Without filtration, tank sediment and manufacturing debris cause sticky regulator response, clogged jets, and inconsistent fuel delivery. The element is reusable — clean it, do not replace it.
• Chemically Inert PTFE Inner Liner: The regulator's documentation says "Upgrade to PTFE-lined fuel hoses for E85." This bundle does exactly that. PTFE (Teflon) is completely resistant to ethanol, gasoline, diesel, and all automotive fuels. Your fuel line stays intact for years, not weeks.
• Hardline Compression Adapters — No Splice Joints: The two 6AN to 3/8" compression fittings create a sealed, mechanical connection between the PTFE hose and the vehicle's existing metal hardlines. No rubber splice hoses, no hose clamps, no leak points. Black anodized aluminum matches the filter and regulator housings.
• Precision You Can See on the Gauge: The adjustable regulator holds pressure steady at your chosen setting with a visible gauge for real-time monitoring. Anodized aluminum body stands up to ethanol blends and road conditions. Vacuum-referenced port available for boosted applications.
• Extreme Temperature and Pressure Headroom: PTFE hose operates from -76°F to 446°F — stable in winter cold starts and engine-bay heat soak alike. Standard rubber hose typically tops out at 257°F; PTFE gives you nearly double the headroom. Rated to 1500 PSI working pressure, far beyond any carbureted system demand.
• 1-Year Warranty & Free Technical Support: EVIL ENERGY stands behind every component. Questions about E85 fuel line routing, filter micron selection, regulator pressure settings, or hardline adapter installation? Our technical support team is here to help.
