hi for some reasion the fuel is draining back overnight on my 1hz, it only happens when i leave it for more then 6 hours.

if i pump the fuel primer up it will start first crank. and there is no other problems with it.

has anybody got any ideas of what might be wrong with it. im thinking air leck or somthing in the injector pump is rooted.

cheers DB

either the o'ring in the hand primer pump is dodgy or your fuel fiter may not be tight enough
