Question

What is right size for an LR3 locking gas cap?

Answer 1

I dont know the size but I can tell you that you will need to go to the dealer and see if they have one because 60 percent of the aftermarket locking gas caps will not seal correctly and you will get a check engine light..........

With the gas the way it is I get around 30 vehicles a week with check engine light on all makes and models due to an incorrect locking gas cap........
