tank sayin half a tank

last owner sayin he not replaced anything to don anything witch aint true cos air intake pipe was off and air box cover loose and fuel filter looks new.

check all fuses and relays all ok no faults shown up got some1 form work over the weekend to bring the fuel drain van over see if he can pull fuel up i think it just a air lock big one.

and i hope it all it is - A good suck
