we dont have Jackaroo here in USA.
sorry! we are USA forum no Holden's here, ever)
you in Australia?
NO actual V6 stated, which one of the 3?
size v6 and , cam count per head, and fueling system there.
NO photo of engine posted, and bam , there it is
and fueling parts, all clear as DAY to me.
it's a no start.
the fuel feed line goes to the pump, why not just look at this line see where it goes? no?
cam belt fresh, spark plugs fresh?

the word PETROL gives you away as does JACKaroo
most are in the tank, but not so on all carb engines sold world wide.
lacking what engine is there, and what fueling system , why post to USA forum >?
all you will get is,
and OFF TRACK .
or like I do, generic MR. OTTO CYCLE Gas engine
