hello from texas. thanks for the add

[rob308]

I've purchased a 1981 k20 awhile back. I've already installed a 350 tbi from a newer truck. The motor has been wired and started. I have a 1989 k20 tbi parts pickup. I'm going to take the tanks and hard lines from donor. I was hoping to remove the wiring from tank to switch, but the mice have chewed them into. I've looked at numerous post trying to find the information as how to wire tanks, switch, and any relays need to make the truck run. Both trucks have a four speed transmissions. Any help would be appreciated.

thanks, Rob

If you look in our Engine Section there is plenty of info on dual tank setups, and there are lots of people here to help.
