I’ve gone down the rabbit hole and can’t find my way out. It all started with a blown radiator replacement and that turned into a birfield rebuild and fuel tank/filler neck replacement. Put everything back together and it wouldn’t stay running. So I changed the fuel filter, charcoal canister, fuel pressure regulator, fuel pump and the pump filter. It starts but as soon as I put it in gear or give it gas quickly it dies. There isn’t any pressure building in the tank....there had been but that stopped once I swapped out the canister. Help! Thanks
