    I've got a project I'm working on thats will be using a Tune Port Injection setup and the fuel pressure before the regulator is around 100 psi or a little less. would this be a problem for the stock electric dual tank switcher in 70's or 80's dual tank pick-ups? the order from tank to engine will be tank(s) switcher, electronic fuel pump, regulator (built into the TPI) then the fuel rail etc. the fuel pump only pushes 100 psi, I dont hink it pulls that hard. This shouldnt affect the switcher valve should it?

    I don't think it would be a problem for the tank selector valve at all.

    This is what I plan to do.

    Whatver you do, do NOT pressurize the switchover valve!!
