3/4 Inch(19mm) ID Fuel Line Hose Ph Lock NBR Rubber Hose Line 300PSI for Automotive Engines Systems (5FT)

Three-quarters of an inch is a large fuel line. At 19mm inside diameter this is filler neck, transfer pump and tank plumbing territory rather than anything feeding an injector rail, and it comes in a five foot (1.52 m) length of NBR rubber.

Both pressure figures, and their basis

The supplier publishes two, and it states what each one is: working pressure 300PSI, burst pressure 1160PSI. That is more than most hose listings in this category give, and both figures are quoted here exactly as printed with no conversion applied. Read them as the supplier's own claims — no standard is named anywhere in the data, no SAE or DIN classification appears, and nothing has been independently verified. The gap between the two figures is the supplier's stated margin, not a licence to work near either.

Minus forty to one hundred and twenty

The stated temperature range is -40°C to 120°C. NBR is a nitrile rubber, which is the usual choice for fuel work because it resists swelling in hydrocarbons where natural rubber does not. Wall thickness is implied by the two diameters given: 19mm inside, 27mm outside, so about four millimetres of wall each side. That thickness is part of why the hose holds its shape through a bend instead of kinking flat.

The fluids the supplier names

Diesel, biodiesel, petrol, oil, grease, water and air — that is the list, and the supplier describes the hose as mainly for fuel supply. Nothing in the source addresses ethanol blends such as E10 or E85, engine coolant, brake fluid or refrigerant, and no suitability for any of those is claimed here. Vehicles named are cars, ships, motorcycles and large trucks.

Key features

• 19mm inside diameter: sized for transfer and filler work, not injector feed.
• 300PSI working, 1160PSI burst: both figures published with their basis stated.
• -40°C to 120°C: the operating range the supplier gives.
• NBR nitrile: the compound the supplier specifies.
• Five foot length: supplied as one continuous run.

Before this hose carries fuel

• Fuel systems are pressurised and fuel is flammable. Choosing hose, clamps and routing that suit your own system is the installer's responsibility, and any fuel line work should be done by someone competent and pressure-checked before the vehicle is driven.
• The pressure and temperature figures are the supplier's, published without reference to any standard. Do not assume a fitting or a clamp is rated to match them.
• Ethanol blends are not mentioned in the source. If your fuel is E10 or E85, confirm compatibility with a supplier who states it.
• The supplier lists helicopters among the applications. That claim is unsupported by anything else in the data and is not repeated as a use for this hose.
• The supplier's own note asks buyers to pay attention to the working conditions when using it. That is worth taking at face value.

Five feet is enough for a tank-to-pump run with a little to trim, and the ratings are at least printed rather than left blank.
