Replacement MERLO diesel fuel caps & locking filler caps

Why you shouldn't buy and fit a Cheap Diesel Filler Cap to your MERLO

Fitting a cheap fuel cap to your MERLO is not recommended. Because all MERLO filler caps are NOT created equal. Many sold online in the UK are cheap imports from the Far East. Ask yourself how they could sell at half the price you might expect to pay on the High Street or from a specialist online seller like us.

But, it's only a diesel cap. Your fuel cap is part of your MOT inspection. It keeps the fuel from spilling out of the tank, should you be involved in an accident. It has to maintain pressure within the fuel tank itself. You wouldn't replace your brakes or steering wheel with a cheap import made from low grade plastics.

Because all our MERLO fuel caps are produced in Europe, to ISO 9001 specification, you know you are fitting a safe, well-made product to your vehicle.

Do you sell fuel caps for older MERLOs?

I dropped my Mercedes petrol cap

Maggie | England

I dropped my Mercedes petrol cap knocking the inside part out of line. With so many caps available for the Mercedes l gave up looking, contacted Mark at Petrolcap. As it wasn't broken he thought we could save it. So l sent photos and he talked me through fixing it. Thank you so much Such a lovey man to talk to.

Great Service
