about the fuel cap company

fuel cap company founder mark smart

A family run business built on trust and service since 2007

The Fuel Cap Company was born out of necessity. Like so many other businesses, it all started when sourcing a quality replacement fuel cap for a friend proved to be far from easy. That was back in 2007. We have been supplying quality fuel caps to our customers ever since. Although the UK remains our largest market, we ship fuel caps all over Europe, to India and Australia and the US and Canada. In fact over the years, we have shipped to over 35 countries from our head office in Oswestry.

Buying from us, you can be assured you are buying a quality product (ISO 9001), manufactured in Europe to OEM standards, from a family run business that thousands of buyers all around the world have come to trust.
