5M Fuel Tank Hose Clip Inline Filter Kit For Webasto/Eberspacher
This kit is best for standard Webasto and Eberspacher diesel heater systems that require a direct fuel-line replacement from the tank to the heater. It includes a 5 m fuel line, an inline diesel filter, five replacement hoses, and multiple hose clips. Choose this if you want a ready-to-install package that includes a filter to help protect the heater from contaminants and a straightforward assembly with compatible diameters for common diesel installations.
Who it’s best for: business owners or DIYers performing a routine fuel-line replacement on compatible Webasto/Eberspacher units. Why selected: it offers a complete set with an inline filter and sufficient hardware to minimize additional shopping trips. Caution: verify the inner and outer diameters match your hose and tank fittings before installation.
4M Flexible Silicone Fuel Line Kit
Best for upgrading aging hoses or replacing a brittle line, this kit uses high-grade green silicone to resist cracking, hardening, and heat. It is designed as a direct replacement for Webasto and Eberspacher air diesel parking heaters, making it suitable for RVs, trucks, or any vehicle with a similar heater. Included are the main 4 m hose, five connection hoses, ten stainless clamps, and a filter, offering a complete overhaul in one purchase.
Who it’s best for: those repairing or preventing leaks in older diesel heating setups. Why selected: silicone construction provides long-term durability in high-heat environments. Caution: silicone hoses have specific installation lengths; ensure the hose diameter and clamp sizes fit your system exactly to avoid leaks.
16.4Ft OEM-Grade Diesel Heater Fuel Line Kit
Best for OEM-style replacements and longer runs, this kit corresponds to multiple Webasto and Eberspacher models, including HL18/24/32, HL90, and Top series variants. It provides the fuel line, inline filter, connecting hoses, and clamps, with clear dimensions to ensure compatibility.

The kit includes two long fuel lines, two filters, 24 pipe clamps, and 12 black connection hoses, which helps minimize downtime during replacements. It’s broadly compatible with most heater tanks and provides durable plastic and metal parts for long-lasting service.
Who it’s best for: operators who value spares and quick replacements to keep downtime minimal. Why selected: the larger bundle reduces shopping trips for consumables. Caution: while compatibility is broad, confirm the exact hose diameters and clamp sizes match your specific model before installation.
5M Tank Hose Clip Kit for Diesel Heaters
Best for broad compatibility with Eberspacher and Webasto heater systems, this kit is designed to replace the fuel tank standpipe with durable rubber and metal construction. It has passed waterproof testing and aims to resist rust and scratches over time. This kit provides long-term service life for secure fuel delivery in varying weather conditions.
Who it’s best for: buyers seeking a robust, weather-resistant fuel tank standpipe replacement. Why selected: the kit emphasizes durability and waterproofing to support outdoor or exposed installations. Caution: verify the exact replacement part numbers (1320399A / 35320A) and your heater model fit before ordering.
Buying Guide: Key Purchase Considerations
- Compatibility: Check that the kit matches your heater model (Webasto or Eberspacher) and the OEM part numbers (e.g., 1320399A, 35320A) listed in the product description.
- Hose Diameter and Length: Confirm inner and outer diameters (ID and OD) to ensure a snug, leak-free fit. Measure the space available for long runs or restricted areas.
- Material Durability: Silicone vs. rubber; silicone hoses resist cracking under heat but may require careful handling during installation. Rubber components should be chosen for robust, weather-resistant conditions.
- Included Accessories: Look for inline filters, clamps, connectors, and spare hoses. A complete kit reduces the need for additional parts and downtime.
- Installation Considerations: Some kits include clamp sets and filters that protect the system from contaminants. Ensure the kit includes all necessary hardware for your installation.
- Maintenance and Longevity: Consider waterproofing or corrosion resistance, especially in exposed or outdoor installations near fuel storage.
Frequently Asked Questions
- What is the primary purpose of a diesel heater fuel line kit?
– To replace or repair the fuel delivery path between the fuel tank and the heater, ensuring reliable fuel supply and reducing leaks. - How do I know which OEM part numbers to match?
– Compare the part numbers listed in the product description (such as 1320399A and 35320A) with your heater’s OEM labels or service manual. - Are silicone fuel lines better than rubber for diesel heaters?
– Silicone offers improved resistance to heat and cracking, which can extend the life of the line in high-temperature environments, though installation should follow manufacturer guidelines. - Is a complete kit preferable to buying individual parts?
– A complete kit reduces search time and potential mismatches, and includes clamps, filters, and hoses needed for a full replacement. - Can these kits be used for multiple heater models?
– Some kits list broad compatibility; always verify your specific heater model and part numbers to ensure a proper fit.
