    how long do u think the v6 should run, running off a jerrycan? my v6gem drank the whole jerry can in a matter of minutes. it hasnt got the o2 sensor connected yet, but i dont think that should matter too much. only other guess i can think of is the aftermarket fuel pump might be pumpin too much pressure in.

    could that be a problem or should the stocko fuel regulator fix that?

    cheers,

    How did you set up the fuel feed and more importantly the fuel return.

    if it drank that much fuel in a few minutes (idling or driving?) i'd imagine it was blowing some serious black smoke out the back.

    i'd be looking at the pressure regulator or maybe a blocked return line (also causing excessive pressure) or a fuel leak worste case scenario.

    i drove a VN V6 home on 5ltrs (5km's), it idled for another 10 mins, did a long burnout,new tyre to zero tread (on private driveway......mine:D ) then idled it to let it cool down and it still didn't run out of fuel.

    yeh its only idling. (no tailshaft or exhaust yet, left manifold not bolted on yet). i can smell petrol from like 40m away from the car. dont see any leaks. will check the return line and fuel lines under car.

    can i install a aftermarket regulator and leave the old one where it is?

    smells like a fuel leak to me. check around the injectors, a faulty 'o' ring could do it.

    if your going to run a aftermarket regulator you would want to get rid of the factory one
