there is a lever on the firewall side of the lift pump. if it's not there then you'll need a new pump or maybe it's time to upgrade to an electric pump to keep up with the 450 hp your after

Ok so I primed the pump but now when I turn the truck on it's pours fuel out the bottom of the filter through the rubber hose

We are all good now. I think I primed too much maybe. Trucks runs way better I'm pretty shocked actually. And can someone tell me how changig fuel filters made my oil pressure reading stable? I replaced the sending unit weeks ago and my pressure would just rise to normal then randomly fall to zero and never trigger the light

the pressure sender wires probably have a small short somewhere (very very common) and you probably hit them while changing the filter.

Thanks. I figured it was just a short but wasn't 100%
