make sure to retain the oil switch in the fuel pump circuit. it is usually just above the oil filter on the TBI trucks, but you can use the oil gallery under the distributor as well. this serves 2 purposes, 1. if your relay dies, once you crank enough to get above 5 psi, the pump will energize from the oil switch alone 2. takes load off the relay contacts for longer contact life.
also don't use regular fuel line in the tank,.you need to get fuel hose rated submersible. usually black hose with a pink stripe on it.
