Hi all,
I just purchased a 1999 HZJ75 with a 140L auxiliary tank. I just don't understand how it works and seek some help.
The seller told me that there is a transfer pump with which I can transfer fuel from the 140L auxiliary tank to the 90L main tank. The pump worked when I purchased the car, but the 2. tank was empty. So I filled up the main tank and used it. A couple days later I filled up both tanks and the vehicle used the fuel from the auxiliary tank only - without me using the transfer pump at all. So I am wondering what kind of setup this is and what happens when the auxiliary tank gets empty. Will the main tank automatically be used and if so, how. As I said in the beginning: the main tank was used when the auxiliary was empty. But how can it be that only the auxiliary tank is used when both tanks are full? I dont understand this. Can anyone give me their two cents worth, please?
Cheers, Axel.
