I didn't think that depressurising the fuel line (per Haynes Manual) would be adequate to remove all possiblity of fuel leakage and as other respondents have testified. The fuel filter is mounted lower than the tank and fuel wants to siphon out anyway, albeit not under pressure. Sure enough, fuel wanted to squirt out as I eased the hose off one end of the old filter. Resigning myself to losing at least some fuel I did the exchange over an old washing up bowl. Gently ease the hoses back from the old filter to the flared sections and then, with the new filter ready, finally disconnect the hoses in a quick clean action. This simply results in a slow trickle of fuel from the tank side. Just as quickly, it should be easy to reconnect both hose ends to the new filter and prevent any further leakage.
Remember to repressurise the system per Haynes manual and she'll start first turn of the key.
For purely scientific reasons I hacksawed the old filter in half (don't tell me you weren't curious?). There is a lot of rolled up cardboard-like material through which the fuel has to travel to get from one end to the other. Unsurprisingly this was filthy. Mazda's 60 000 mile change is a bit optomistic and for the price more frequent changes are justified.
The product? 5/5 - it's identical to the original I removed.
