Recently my ute developed some new "features" that interferes with the basic principle of a vehicle, getting from point A to point B.

I'll take a quick drive to point B without any problems, but returning to point A seems to get a bit more troublesome every now and them. I'll start up the ute with no problem and drive for oh about 300m and then nothing, no more throttle. After comming to a full stop and taking a closer look under the hood i notice there's no fuel in the carb. This seems odd I'm sure the last time i checked there was still half a tank of gas left. With further inspection I notice there is also berley any fuel in the fuel filter. So my first thought were broken fuelgauge....wrong.

So sitting next to the road for 30mins or so waiting for my lift I decide to give her one more go and bam she starts again WTF? So without delay i make spirited run back to point A.

Now, are these common symetoms for machanical fuelpumps nearing the end of there lives or do I need to go look for rocks in my fueltank?

TIA
