One of my major problems is the gas gauge on my truck does not function.
So you are saying take the Ford setup and plum pressure line into the Toyota vent line. Then, put a switch in cab and flip when it gets low? I thought about doing that setup, but after reading about OOPS' setup and doing some reading and PMing on pirate, that setup only has about a 50/50 chance of working right. If it is not setup just right, the toy tank will overflow when the pump is off and will flood the charcoal canister and do bad things. Solution is a ball valve, and at that point I might as well make it all set up in a nifty box in the bed next to my battery box. Ball valve, Ford fuel gauge, switch w/ relay. I think I am going to run the fuel filler neck for the Ford tank to the bed as well.
