High Pressure Fuel Line Hose 5-15FT 500PSI E85 NBR

Q: Which size Red Fuel Line Hose should I use to feed a carbureted small-block V8?

3\/8\u0026quot; is the common supply size on carbureted V8s; many GM trucks, for example, use a 3\/8\u0026quot; feed with a 5\/16\u0026quot; return. A 3\/8\u0026quot; red NBR hose slips onto a 3\/8\u0026quot; barb or a -6AN push-lock fitting. A Holley-style carburetor typically wants about 6 psi, so the hose rating is never the limit; the pump and regulator set the pressure.

DESCRIPTION

Red NBR Fuel Hose · Classic and Carbureted Fuel Lines

Red Rubber Fuel Line Hose for Replacing Old Feed Lines on Carbureted Vehicles

Original rubber fuel hose on older trucks and cars hardens and cracks with age, and modern ethanol-blended gas speeds that up. EVIL ENERGY red high pressure fuel line hose replaces those sections with an ethanol-resistant NBR tube, a polyester braid and a 500 PSI working rating, in 1/4", 5/16" and 3/8" ID to match factory steel lines.

When Does a Rubber Fuel Line Need Replacing?

Squeeze and bend each rubber section of the fuel system. Any one of these signs means the hose is due:

Sign 1

Hard or Brittle Rubber

Old hose feels stiff or rock-hard instead of pliable when squeezed between your fingers.

Sign 2

Cracks When Bent

Fine surface cracks open up when the hose is flexed, especially near the clamps.

Sign 3

Fuel Smell or Wet Clamps

A raw gas odor around the engine or a damp, stained joint points to seepage.

Sign 4

Hard Starts or No-Starts

A leaking or air-drawing feed line can leave the carburetor short of fuel.

Which Fuel Line Sections Does the Red EN854-1TE Hose Replace?

Red EN854-1TE rubber fuel line hose coil with four stainless clamps for replacing old feed lines

On a typical carbureted vehicle, short rubber fuel line sections join the steel lines to the tank, the fuel pump and the carburetor. The red EN854-1TE fuel hose is cut to length for each of those joints, and every roll includes four stainless steel hose clamps. Matching hose barb fittings help where an original connection is damaged or missing.

Where Does Rubber Fuel Hose Sit in a Carbureted Fuel System?

Follow the fuel from tank to carburetor. The red points are the rubber sections worth checking and replacing together.

Tank sending unit outlet

Short hose from the sending unit tube to the steel line, often hidden above the tank.

Steel fuel line along the frame

Rigid line; inspect for rust but no hose here.

Steel line to fuel pump inlet

Flex section that absorbs engine movement; a common crack point.

Fuel pump outlet to filter

Short pressure-side jumper on mechanical or electric pumps.

Filter to carburetor inlet

Final feed section, close to engine heat.

Replacing all rubber sections at once costs little more than fixing one and avoids the next one failing soon after.

How Is the Red NBR Fuel Hose Made to Outlast Old Rubber?

A replacement only makes sense if it holds up better than what came off. These points cover the material, the pressure margin, the fit on steel lines and the other jobs the red nitrile fuel line can take on.

Ethanol-Resistant NBR Instead of Aging Factory Rubber

Gasoline with ethanol attacks older hose compounds, which is why lines on classic cars harden faster today than they used to. The red NBR fuel line uses nitrile on both the fuel side and the outer cover, around a woven polyester braid, and is rated for E85 as well as pump gas, diesel and biodiesel.

Red rubber fuel hose rated 500 psi working and 1720 psi burst compared with an unmarked hose

Pressure Rating Printed on Every Foot

A carburetor typically runs around 6 psi, and stock mechanical pumps work in the same single-digit range. The red 500 PSI fuel hose is rated far above that, so a later switch to an electric pump or a fuel-injection conversion will not outgrow the line. The rating and the EN 854-1TE marking are printed along the cover, so every cut piece stays identified.

Hold carburetor pressure where it belongs with a carburetor fuel delivery kit.

Splicing Red Hose onto Steel Fuel Lines

1Cut out the old rubber and clean the steel line ends.

2Check the bead or flare on each steel end; it keeps the hose from walking off.

3Slide on at least 1 inch past the bead, using a little engine oil.

4Clamp behind the bead on both ends and tighten until snug.

5Run the engine and recheck for seepage once it is warm.

How to Measure Your Steel Fuel Line Before Ordering

The hose ID must match the outside diameter of the steel line or barb it slides over.

Measure 1

Read the Steel Line OD

0.25" (6.35 mm) · order 1/4" hose

0.31" (7.94 mm) · order 5/16" hose

0.375" (9.53 mm) · order 3/8" hose

A caliper gives the cleanest reading; measure next to the bead, not on it.

Measure 2

Count the Sections

Note each rubber joint from tank to carb

Add the lengths plus 2 inches per section

Feed and return lines often differ in size

Many builds share one 5 ft roll across several short jumpers.

Measure 3

Plan the Route

Keep hose clear of exhaust and headers

Stay above the 2.56–3.15" bend radius

Support long runs so they cannot rub

Clips and separators from our hose management range keep lines in place. Add a fuel filter while the system is open.

Why Run Red Hose on the Fuel Supply Side?

Red reads as the pressure side at a glance: using the red fuel line hose for supply and another color for return or vapor lines makes future inspections faster and avoids mixing lines up after a repair.

FAQS

Q: Is the Red NBR Fuel Hose a good replacement for original rubber fuel line on a classic car running ethanol gas?
A: Yes. Original rubber hose on older vehicles was not made for today's ethanol blends, and owners report replacement lines turning hard within a year or two when the compound is wrong. The red hose uses an NBR tube rated for E85, so it handles E10 pump gas comfortably. Replace every rubber section from the tank sending unit to the carburetor at the same time, since they have all aged together. If you later add an electric pump, set carburetor pressure with one of our adjustable fuel pressure regulators.

Q: Which size Red Fuel Line Hose should I use to feed a carbureted small-block V8?
A: 3/8" is the common supply size on carbureted V8s; many GM trucks, for example, use a 3/8" feed with a 5/16" return. A 3/8" red NBR hose slips onto a 3/8" barb or a -6AN push-lock fitting. A Holley-style carburetor typically wants about 6 psi, so the hose rating is never the limit; the pump and regulator set the pressure.

Q: Is the Red NBR Fuel Hose safe for diesel and biodiesel?
A: Yes. The NBR tube is rated for diesel, biodiesel, gasoline and E85, so the same red hose works on diesel trucks, generators and transfer setups. Diesel lift-pump and return circuits run at low pressure, well inside the hose rating.

Q: How do I replace a cracked rubber section between two steel fuel lines with Red Fuel Line Hose?
A: Measure the outside diameter of the steel line, since that sets the hose ID you need: 5/16" or 3/8" steel line takes 5/16" or 3/8" hose. Cut out the damaged rubber, make sure the steel ends have a bead or flare to clamp behind, push the red hose on at least 1" past the bead, and clamp each end behind the bead. On fuel-injected systems, recheck both clamps after the engine has reached operating temperature.

Q: How much heat can the Red High Pressure Fuel Line Hose take near the engine?
A: The red hose is rated for continuous service from -40°F to 212°F (-40°C to 100°C). That covers normal under-hood temperatures, but exhaust manifolds, headers and turbo housings run far hotter, so route the line away from them and add a heat sleeve where it must pass close by.

Q: What do the 500 psi and 1720 psi ratings on the Red Fuel Line Hose mean?
A: 500 psi is the maximum continuous working pressure. 1720 psi is the burst pressure measured in testing, about 3.4 times the working rating. Both numbers exceed the EN 854-1TE class minimums, which call for 25 bar (about 363 psi) working and 100 bar (about 1450 psi) burst on 1/4" hose, and 20 bar (about 290 psi) working and 80 bar (about 1160 psi) burst on 5/16" and 3/8" hose.

Q: Does the Red Fuel Line Hose come with fittings?
A: The red hose ships with four stainless steel hose clamps, enough for two clamped connections. AN fittings are sold separately: -4AN push-lock ends fit the 1/4" hose and -6AN ends fit the 3/8" hose. The black version of this hose is also offered as a -4AN or -6AN kit with eight push-lock hose ends included.

Q: How do I know when a red rubber fuel line needs replacing?
A: Bend a section of the hose by hand and check near each clamp. Replace it if the rubber feels hard or brittle, shows surface cracks when flexed, feels soft or swollen, or if there is wetness or a fuel smell at a joint. Ethanol-blended fuel makes regular checks more worthwhile, especially on hose more than a few years old.

Q: Can the Red NBR Fuel Hose be used for a fuel return line as well as supply?
A: Yes, the construction and rating are identical for supply and return duty. Many builders simply use a different color for the return so the two lines are easy to tell apart; for dedicated return plumbing, see our fuel return lines.

Q: Can I run the Red High Pressure Fuel Line from an electric inline fuel pump mounted on the frame?
A: Yes. Use the red hose on both the inlet and outlet side of a frame-mounted pump, keeping the inlet as short and straight as possible so the pump does not starve. Mount the pump close to the tank and below its outlet when you can, and choose the hose ID to match the pump ports. For pump options, see our electric fuel pumps.
