How to measure ID

Measure the pipe, not the old hose

Heat and age make a used hose swell and go out of round. Take your reading across the metal outlet the hose slides onto — that measurement is your ID.

Use vernier calipers

Set the outer jaws across the widest point of the pipe. A tape measure round a curve reads low by a millimetre or two — enough to buy the wrong size.

Take three readings, keep the largest

Rotate 60° between each. If they disagree the pipe is oval; size to the biggest figure so the hose still seals.

Round to the nearest listed bore

Never go up: a bore wider than the fitting will not grip, whatever the hose is made of. If you land between listed sizes take the smaller bore, and secure it with a clip.

Order by ID, always. Every hose on this site is listed by internal diameter. OD is given for clearance only — it changes with wall thickness and ply count, so it is never the ordering size. On reducers, quote both ends, largest first.

Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

What is it, and what does it fit?

A direct-fit silicone blanking hose for this Land Rover engine. It is listed against OE part number PYB500040, which is the most reliable way to match. Check the model, engine and year range on this page against your vehicle before ordering.

How do I make sure it fits my car?

Match on model, engine and year or facelift, because hoses often change mid-generation. The most certain method is the OE part number - PYB500040 on this listing - stamped or printed on the part you are removing. If you cannot find one, send us photos of the old hose with a tape measure alongside, or your registration, and we will confirm.

Is it compatible with E5 and E10 petrol?

Yes - it is built to fuel-rated specification and handles modern ethanol-blended petrol. That is the main reason to replace an original hose on an older vehicle: ethanol attacks unsuitable rubber from the inside, so a line can look perfectly sound externally while breaking down internally and shedding debris into the fuel system.

What are the symptoms of a failing fuel hose?

A fuel smell around the vehicle, fuel staining or damp on the underside, and difficulty filling without the pump cutting out. On a car stored over winter the smell in a closed garage is usually the first sign. Do not put off a fuel leak in a hot engine bay.

What colours are available?

black and blue. The colour is cosmetic - construction and rating are identical. If you are doing several hoses on the same vehicle, order them together so the shades match.

Does it come with clips?

Some of our listings offer clips as an option at checkout - check the options on this page. Where they are not included, we stock stainless worm drive clips and T-bolt clamps in every matching size. Always renew clips with a hose: old ones lose tension and corrode where you cannot see.
