A self-regulating fuel level equalizing system for internal combustion engines of vehicles comprising a plurality of spaced apart fuel tanks, feed conduits having about equal length, about equal inner diameter, and about equal fuel flow restriction and having lower portions with open ends each disposed at about the same level for automatic preferential fuel withdrawal from the fuller of said tanks, housed within and extending from lower portions of each of said tanks through an upper portion of each of said tanks and devoid of external bottom connections with said tanks and each coupled to a fuel pump, a fuel pump for preferentially withdrawing fuel from the fuller of said tanks through said feed conduits and supplying at least a portion of said fuel to a said engine, distribution means for feeding said fuel from said fuel pump to said engine, return conduits separate from said feed conduits having about equal length, about equal inner diameter, and about equal fuel flow restriction, and having lower portions with open ends each disposed at about the same level in said tanks for automatic preferential fuel return to the less full of said tanks, housed within and extending from lower portions of each of said tanks through and upper portion of each of said tanks and coupled to said fuel pump for preferentially returning any unused portion of said withdrawn fuel to the less full of said tanks, said preferential fuel withdrawing and returning automatically coacting to maintain an about equal fuel level in said fuel tanks.
