NousCap Fitting & Operating Instructions
Fitting Your NousCap
- Remove NousCap from packaging.
- Remove the existing fuel cap from your vehicle.
- First check that you have purchased the correct NousCap in relation to the fuel used in your vehicle.
If your vehicle has a diesel engine the NousCap should be black and yellow in colour and have a “D” on the NousCap plug
If your vehicle has a petrol engine the NousCap should be green and yellow in colour and have a “P” on the NousCap plug. - Check that the NousCap has the same fitting arrangements as your existing fuel cap.
- Fit NousCap into the fuel filler neck of your vehicle and tighten in a clockwise direction.
- Once tight the NousCap should ‘click’ and then feel loose.
- If you can turn the NousCap in either direction without it coming away from the vehicles filler neck then you have successfully and correctly fitted it.
