JPI 450 Fuel scan repair

[Rodr]

does anyone know of a repair establishment that would or could check a JPI 450 fuel scan instrument in OZ before sending back to USA .

 

It works ok while fuel flowing through it however will not hold memory and brings up a 2047 litre used fig on most start ups ,this doesn't change on usage! Bit of a queer one any ideas?
