How to eliminate Td5 fuel leaks - pictures

<span>Safety first – disconnect the negative lead from the battery to power down the electrical systems before opening fuel lines.</span>

<span>Three wheels are chocked and the rear right corner is supported on an axle stand, after being raised with the trolley jack. Gear and handbrake engaged.</span>

<span>Often the green banded (top) HP fuel line from the tank to the fuel filter housing is the problem, but this had been replaced.</span>

<span>The next area to check was the fuel filter and its water drain, inside the right hand rear wheel arch, usually with a steel cover fitted.</span>

<span>Stains, but no leaks at the filter to housing seal but, more significantly, from the top of the fuel housing through the metal casting.</span>

<span>The filter-to-housing joint, and this lower water trap, seemed to be leak free, though the grime suggested the filter was quite old.</span>

<span>After thorough cleaning, the four fuel line bayonet connectors were detached from the fuel filter housing.</span>

<span>The new fuel filter housing is supplied with a fresh fuel filter and water trap. You will need your VIN when ordering, as there are two variants.</span>

<span>New stub pipes also come with the fuel housing kit, as well as new copper crush washers, so no need to salvage the old fittings.</span>

<span>With the housing bolted to the chassis, and pipes and sensor leads reconnected, the Discovery fuel system is leak free once again – job done.</span>
