A buddy of mine suggested i look up something he's seen done on other mid 80's trucks (not sure if its been done on toyota motorhome). I have a 89 itasca with dual fuel tanks. I have to pull over, open lids and flip switches and it transfers gas in rear backup tank to front tank in case of emergency. I was wondering if there was a way to bypass the pump and just have the truck pull fuel from both tanks at the same time? I'm not even sure if this is possible. Thanks for any input.
