| Filler Hose & Reducers | Join tank to filler | 38–51 mm ID; reducers available | OE swaps, tray/canopy tanks | Use fuel-rated hose & lined clamps |
| Vent/Rollover Valve | Vent & tip-over shutoff | 8–12 mm barb; one-way | All petrol/diesel tanks | Route high and away from splash |
| Breather Filter | Dust/splash protection | 8–12 mm barb | Dusty, wet touring | Service filter media periodically |
| Quick-Connect Couplings | Clean line disconnects | 8/10/12 mm; SAE/BSP/metric | Serviceable installs | Match standard & seal material |
| Sender Unit & Seal | Accurate fuel gauging | Ohms range model-specific | Replacement tanks | Check gauge calibration |
| Mounting Straps/Hardware | Secure the tank | Vehicle-specific | All tanks | Use high-tensile bolts; re-torque |
| Skid/Stone Guard | Impact protection | Steel/Alloy | Rocky tracks | Mind clearance & drainage |
Buyer’s Checklist – How to Choose
- Confirm fuel compatibility (diesel/petrol, E10/E85) and seal material (Viton/NBR)
- Match hose IDs (filler 38–51 mm; vents 8–12 mm) and reducer sizes
- Choose the correct thread/standard for fittings (BSP, NPT, metric, SAE quick-connect)
- Integrate EVAP components on petrol vehicles; use proper rollover valves on all
- Plan routing & heat shielding to avoid exhausts, sharp edges and pinch points
Fitment & Compatibility Guide
Measure interfaces and plan the plumbing before ordering.
- Filler path: verify neck angle and bay space; avoid kinks and sag points
- Venting: mount rollover valves vertical; route breathers high with drip loops
- Senders: match resistance curve to OE gauge or add an adapter/interface
- Fittings: confirm barb/OD sizes and seal types for quick-connects/bulkheads
- Protection: use skids/guards where the tank sits ahead of axle or near rock strike zones
Care & Durability
- Inspect hoses, clamps and seals after corrugations; re-torque hardware
- Check for fuel smell or dampness at joints; replace aged hoses
- Clean/replace breather filters; keep vent lines clear
- Rinse mud/salt; touch up coatings on steel guards/straps
- Test gauge/low-fuel warnings after service or changes
Upgrade Sequence Roadmap
- Replace old filler & vent hoses with fuel-rated lines and lined clamps
- Add rollover valve + breather filter and tidy routing with bulkhead fittings
- Fit new sender & seal or gauge adapter for accurate readings
- Install quick-connects for easy service and a skid/stone guard where exposed
- Finish with heat shielding and labelled lines for future maintenance

FAQ – Fuel Tank Accessories
- What size hoses do I need for filler and vent lines?
- Most 4x4s use 38–51 mm ID filler hose and 8–12 mm ID vent lines. Measure your necks and barbs to be sure.
- Do petrol vehicles require EVAP-specific parts?
- Yes. Use EVAP-compatible valves/lines and route vents correctly to avoid fault codes or fuel smell.
- What does a rollover valve do?
- It allows normal venting but closes if the vehicle tips, helping prevent fuel leakage in a roll-over.
- Which seal materials should I choose?
- Viton (FKM) handles petrol/ethanol blends well; NBR is common for diesel. Match seals to your fuel and temperature range.
- Are quick-connect fittings universal?
- No. They come in different standards and sizes (SAE, BSP, metric). Match both size and seal type to your lines.
- How do I eliminate fuel smell after an install?
- Recheck hose clamps, sender seal, and vent routing. Add a breather filter and ensure EVAP lines are correctly integrated.
- Do I need a skid plate or guard?
- Recommended if the tank sits low, ahead of the axle or near rock strike zones to protect against punctures and dents.
- Can I reuse my original sender unit?
- Often yes, but confirm resistance curve and float geometry match the tank. Replace seals and verify gauge calibration.
