The EVIL ENERGY Carburetor Fuel Pressure Regulator Kit ends the guesswork with an adjustable 4.5–9 PSI range. Each bundle pairs the regulator with a 20 FT fuel line already matched to its outlets — NBR rubber hose for gasoline and diesel, or PTFE braided hose for E85 and high-pressure builds. Both ship complete: gauge, bracket, fittings and clamps, nothing else to source. Fitment Fits low-pressure carbureted fuel systems with a mechanical or low-pressure electric pump: Classic muscle cars & hot rods — 4-barrel V8 engines Motorcycles, ATVs & small engines — generators, pumps, industrial engines Custom carbureted builds — any setup needing pressure dialed to the carburetor spec Not for EFI / fuel injection. Running E85 or alcohol? Choose the PTFE variant — the NBR hose is not rated for it. Key Features PICK YOUR HOSE BY FUEL — NBR variant: 3/8 in (6AN) push-lock rubber hose, 750/1450 PSI, -4–212°F — gasoline & diesel only. PTFE variant: 6AN braided hose, 1500/4500 PSI, -76–446°F — rated for E85, alcohol and high-heat. 6061-T6 ALUMINUM BODY: one 1/8 in NPT gauge port + two 3/8 in NPT feed / return ports; non-vacuum design holds steady pressure across the RPM range. COMPLETE KIT, NO EXTRAS: regulator, gauge, bracket, port plug, outlet fittings (barb or 6AN), Allen key, sealant tape and screws; hose includes clamps or AN hose ends. CARBURETOR ONLY: built for low-pressure carbureted systems (muscle cars, hot rods, motorcycles, generators); not an EFI regulator. NBR Rubber vs PTFE: Which Variant Do You Need? The two variants are not interchangeable — your fuel decides: NBR rubber — gasoline / diesel, lowest cost, push-lock + clamps, flexible routing. Sold separately here. Not for E85. PTFE braided — E85, alcohol, max pressure & heat headroom; rigid hose with 0°/45°/90°/180° AN ends. Full PTFE range here. Barb vs AN: Why the Two Variants Use Different Outlets Barb and AN solve different jobs, and mixing them is the #1 install failure. A barb + clamp seals soft push-lock rubber hose; an AN 37° flare seals rigid braided PTFE metal-to-metal — no clamp seals braid, and a barb in PTFE always leaks. That is why each bundle is a fixed pair: NBR ships 3/8 NPT→barb adapters, PTFE ships 3/8 NPT→6AN. The 3/8 NPT port plug blocks the second feed port if you need one outlet. Package Contents NBR Rubber Variant: 1 × Regulator (3/8 NPT→barb, non-vacuum) · 4.5–9 PSI gauge · bracket · port plug · Allen key + tape · screws · 20 FT 3/8 in (6AN) NBR hose · 10 clamps PTFE Braided Variant: 1 × Regulator (3/8 NPT→6AN, non-vacuum) · 4.5–9 PSI gauge · bracket · port plug · Allen key + tape · screws · 20 FT 6AN PTFE line with 0°/45°/90°/180° AN ends Why Choose EVIL ENERGY Carburetor Fuel Pressure Regulator Kit? Matched regulator + hose in one box — no barb/AN mismatch, no second order, no leaking joint. 4.5–9 PSI adjustment with gauge — set to spec, stop flooding and lean-out at WOT. 6061-T6 aluminum — light, corrosion-resistant, adapts to most carbureted systems. NBR or PTFE by fuel — 750/1450 PSI rubber for gas/diesel, 1500/4500 PSI braided for E85 & heat. 1-year warranty, 90-day returns, free fitment support at support@ievilenergy.com.
