Our "Colossus" range of fuel pumps are proven and recommended by many tuning companies and mappers in the UK and around the world and have gained a reputation for been the best on the market. All pumps are individually tested and serial numbered and results recorded. This means each pump we dispatch we know not only is a working pump but also has passed our stringent testing on flow rates and currant draw. On cheaper pumps available on the likes of eBay the pumps can flow pretty well but do draw unsafe high amounts of current which can damage wiring.
