Designed as an electrical replacement for Triumphs with manual fuel pumps
Also suits power tuned carburettor equipped Triumphs for which the standard fuel pump may not be able to maintain adequate fuel pressure at higher engine speeds.
Electric pumps can be fitted to the front or rear of the car, but ideally not higher than 70cm from the fuel tank bottom feed. Electric fuel pumps provide further benefits in alleviating problems associated with vapour lock, hot starting, and give constant fuel pressure even at high temperatures.
If converting from an engine driven pump be sure to fit a fuel filter before the pump - any dirt or grit larger than a grain of sand will shortly wreck an electric pump.
