Ok, the deal is i have a VU SS series 2 LS1 utility, couple of days ago i filled up the fuel tank all the the way and that night i hit the highway and pulled out 190kms in a night, the gauge is still reading full? Today i took it to Holden to see if they could re-calibrate the sender via the dash cluster ecu clip and nothing? Know ive been told to buy from Holden a new MRA unit which is $334? Is a MRA unit a Fuel Sender? Any help with this would be appreciated guys :-) Cheers Matt
