    Is this a ground wire for hydraulic pump?

    1978 Mercruiser, serial number 3773776. Motor was removed in a shop. For various reasons, I am putting back in. This is the only wire I’m not sure of.

    Merc 140 fuel pump install, no ros?

    Oops….good eye! I forgot to mention that the clear line you see going line going from the pump to the “tank” is strictly there for a test run while motor is out of boat. It will go to a small gas can. Actual fuel line is to code. Great catch.

    I purchased the fitting at a store that specializes in fittings and hoses. I specified it was for fuel and he assured me it was the correct hose

    Merc 140 fuel pump install, no ros?

    So doing some research. It’s definitely a marine carb, parts number directs to a Rochester carb for Mercruiser. Nothing actually written about retrofitting a card pre fuel vent. Found a picture where it seems fuel vent line connects to carb and where mine simply has a bolt in it. I’ve attached...

    I will have to see if it is possible to retrofit a fixture on the carb because, as it stands, there is no fixture to plug the vent tube that would come from the pump. I will study newer schematics to see where it is supposed to fit.
