The best oil burner fuel line is one that matches the burner’s required length, tubing size, and fitting type. The Beckett 5636 is a short 6-1/2-inch line option, while the Beckett 5628 and a 5628-style copper assembly are 9-1/2-inch choices for applications that call for that specification. The other products listed are not direct oil-burner fuel-line replacements: one is small-engine hose and one is an air-tube assembly. Check your burner documentation and existing fittings before choosing a part.

|---|---|---|
| Beckett 5636 | A buyer seeking a 6-1/2-inch oil line | Model 5636; 6-1/2-inch product name |
| Beckett 5628 | A buyer needing a 9-1/2-inch line for an AFII burner | 3/16 inch by 9-1/2 inches |
| 5628 Copper Oil Line | A buyer matching a 9-1/2-inch line with female flare fittings | 3/16-inch female flare fittings |
| GoaMotors Fuel Line Kit | Small-engine hose and parts, not an oil-burner line | Four hose sizes and small-engine components |
| Beckett AF Air Tube Assembly | A buyer needing an air-tube component, not a fuel line | 5-3/8 inches; without head |
Beckett 5636 6-1/2-Inch Oil Line
Best for: A buyer whose burner setup calls for a 6-1/2-inch oil line and whose existing connection details match the replacement part. The product name identifies it as a Beckett 5636 line, and the listed model number is 5636.
The listed country of origin is the United States. Package dimensions are given as 1.0 by 1.0 by 7.0 inches; these are package dimensions, not a substitute for checking the actual line length or connection specifications. The product title supplies the 6-1/2-inch length.
- Choose this if you have confirmed that the required line length is 6-1/2 inches.
- Compare the fittings and routing with your burner’s specifications before ordering.
Limitation: The supplied product details do not specify the fitting type or tubing diameter. Avoid choosing it based on length alone if those details are unknown.
Beckett 5628 9-1/2-Inch Oil Line
Best for: Buyers looking for a 9-1/2-inch line identified for a Beckett AFII burner. The product name specifies both a 3/16-inch measurement and a 9-1/2-inch length, making those dimensions central comparison points.
This is a better match than a shorter line when the burner’s required routing length is 9-1/2 inches. Confirm how the listed 3/16-inch dimension corresponds to your existing line and verify the end connection before ordering. Product details provided here do not include additional installation or fitting information.
- Choose this if the burner documentation calls for the listed AFII line and dimensions.
- Compare the overall length and connection type with the part being replaced.
Limitation: The supplied listing information does not describe the fitting style. Do not assume a connection type based only on the product name.
5628 Copper Oil Line With Female Flare Fittings
Best for: A buyer matching a 9-1/2-inch copper oil line with 3/16-inch female flare tube fittings. The listing describes it as a replacement assembly, identifies part number 5628, and states that it is intended for Beckett oil burners requiring a 9-1/2-inch fuel-routing line.
The stated dimensions and fitting style make this option easier to compare when those exact specifications are needed. Choose it if your burner’s required line length and connection details match the listing. Its stated compatibility is specific to Beckett burners requiring the described 9-1/2-inch routing line; it should not be treated as a universal oil line.
- Listed overall length: 9-1/2 inches.
- Listed fittings: standard 3/16-inch female flare tube fittings.
- Listed material: copper.
Limitation: The stated fit is for burners requiring these specifications. Confirm the burner model and connection requirements rather than relying on the part number alone.
GoaMotors Small-Engine Fuel Line Kit
Best for: Small-engine owners seeking assorted fuel hose, filters, and primer bulbs for the listed types of equipment. This kit includes four hose sizes, with four feet of each size, plus four fuel filters and five primer bulbs. The listing names chainsaws, trimmers, blowers, and brushcutters among its intended applications.
This product is included for comparison, not as a recommendation for an oil burner. Its features describe small-engine hose and components, including dimensions in millimeters and replacement references for small-engine parts. An oil burner has its own fuel-line requirements, so a hose kit intended for small engines should not be selected as a substitute without explicit confirmation from the burner manufacturer or a qualified technician.
- Four listed hose sizes range from 2 mm by 3.5 mm to 3 mm by 6 mm.
- Includes filters and primer bulbs for listed small-engine applications.
Limitation: The product is described for small engines, not oil burners. Avoid this if you need a specified Beckett oil-burner line or burner-rated assembly.
Beckett AF Air Tube Assembly
Best for: A buyer specifically looking for a Beckett AF air-tube assembly measuring 5-3/8 inches and supplied without a head. This product is relevant to burner-component research, but its name identifies an air-tube assembly rather than a fuel line.
Do not confuse the air tube with the line that carries oil to the burner. The listed 5-3/8-inch dimension refers to this assembly as identified in its name; it does not indicate a fuel-line length. Choose it only when an air-tube component is the required part and the burner specifications match.
- Product type: AF air-tube assembly.
- Listed configuration: without head.
- Listed length: 5-3/8 inches.
Limitation: This is not described as an oil line. Avoid it if your repair requires a fuel-carrying tube or line assembly.
Buying Guide: How to Choose an Oil Burner Fuel Line
Which line length should you choose?
Start with the burner’s parts documentation or the exact replacement-part number. The products listed here include a 6-1/2-inch line and 9-1/2-inch line options. Those lengths are not interchangeable by default. A line that is too short may not follow the required route, while extra length can create an unsuitable installation. Measure the existing part only as a cross-check; confirm the required specification before buying.
Why do fitting type and diameter matter?
A line must match the burner’s connection requirements as well as its length. One listing explicitly identifies 3/16-inch female flare fittings, while another identifies a 3/16-inch measurement without specifying the fitting style in the supplied details. Do not assume that matching a number means the ends will connect. Check the replacement part number, fitting type, and tubing specification against the burner documentation.
Should you choose a copper assembly or flexible hose?
The listed Beckett products are identified as oil-line assemblies, and one listing specifically describes a copper line with flare fittings. The GoaMotors kit is described as small-engine hose with filters and primer bulbs. These product categories serve different stated applications. Do not substitute general-purpose or small-engine hose for a burner line unless the burner manufacturer or a qualified technician confirms that it is suitable.
How can you avoid ordering the wrong burner part?
- Record the burner model and the existing part number, if available.
- Confirm the required line length, diameter, fitting type, and routing.
- Distinguish a fuel line from nearby burner components such as an air tube.
- Use product titles and stated features as checks, not as a replacement for the burner’s parts documentation.
- Ask a qualified heating professional if the existing fitting, fuel path, or required part is unclear.
When should a fuel-line replacement be handled by a professional?
Oil-burner fuel connections need to be correctly fitted and checked for leakage. If you are uncertain about the part, connection, installation procedure, or safe operation after replacement, stop and contact a qualified heating professional. Do not operate equipment with a suspected leak or an unverified fuel connection.
Frequently Asked Questions
What is the difference between the Beckett 5636 and 5628 lines?
The product names identify the 5636 as a 6-1/2-inch oil line and the 5628 as a 9-1/2-inch line with a 3/16-inch measurement. The 5628 listing also identifies it for an AFII burner. Verify the exact required part and fittings before choosing.
Does the 5628 copper line include flare fittings?
Its listing specifies 3/16-inch female flare tube fittings and a 9-1/2-inch overall length. Confirm that those specifications match the burner connection and required routing.
Can small-engine fuel hose replace an oil-burner fuel line?
The GoaMotors kit is described for small engines, including chainsaws, trimmers, blowers, and brushcutters. The supplied details do not establish it as suitable for an oil burner, so do not use it as a substitute without manufacturer or professional confirmation.
Is the Beckett AF air tube an oil line?
No. The product is identified as an air-tube assembly without a head. It is a different component from a fuel line.
What should I check before ordering an oil burner line?
Check the burner model, part number, required length, tube size, fitting type, and routing. Match all available specifications rather than choosing by length alone.
