it sounds like your problem lies elswhere than the fuel supply.
That's plenty of fuel to get it started if everything else is running right. I've had similar problems with mine which turned out to be the old earthing issues. Wolf's don't like much voltage drop in my experience. If your batteries a bit suspect, under cranking voltage can drop enough to make sensing the crank/dizzy pulses difficult to 'see' to the wolf, (even if the ECU doesn't reset) once running the alternator can pump a bit of extra surface charge on the battery which gives you a bit more kick the next start, plus the motor already being warm would fire on the first spark. If you find sometimes it wants to go as you let go of the key? if manual try parking it on a hill sometime, letting it cool down, and try roll starting from cold. This will not put any stress on the battery etc since the started is not in use and if it starts and runs you've found your problem, otherwise not sure, but def seems your problem is not fuel.
