Re: 1967 E parts?
"We think is a 1967" isn't good enough. You have to know what year it is, not guess. Furthermore, you have to know if it has the original fuel pump.
OK, lets just assume both answers are yes. In that case, are you talking about the filter cap? Or the hose nipples? The filter cap is part number 311203, and the gasket is 311202. Both are available from any Evinrude dealer. Or anyplace on-line that sells genuine Evinrude factory parts. But if it is the hose nipple that is cracked, that is part of the pump and you have to buy a complete pump.
Having said all that, some pumps have the inlet hose nipple as part of the filter cap. That is replaceable (different number than I just gave you). The fuel outlet hose nipple is part of the pump and not replaceable.
Again-------- you need to know what you have, and exactly what is broken.
