Fuel tank

[Brian75]

Hi all, I am new to this. Bought my first patrol 2 months ago. A 2015 ST N-Trek Y61. I have a question about the fuel tanks. I was told the main was 80lts and sub 45lts. I have drained the sub tank twice now and most I can fill into it is 32lts. Can some one tell me what the deal is. Thanks Brian

95 Main and 30 in the sub mate.

Standard tankage is 90 rear and 32 sub tank easy to upgrade to 148 rear and 80 sub which is what I have done
