They used a vent valve in th cap. Should be 'open' normally,'closed' only when fording. Summertime now, things warm up, if vent is closed you will vapor lock. Otherwise M37 fuel system is like any other car- pumps do go bad, tank pickups do get plugged up, inner layer of fuel hose goes bad where somebody cut the steel line and slipped rubber over it without any de-burring, filters plug by a tankful of dirty gas......
