    Serial number

    The US single flare and double flare are completely different fittings, same with metric bubble flare. I would use the marine fuel hose from amazon you mentioned .

    Mercruiser 4.3 oil gauge mystery

    A switch and a sender are two different things. A switch like the oil pressure switch used for the alarm circuit will be open when the pressure is above the set point ( 4 or 7 psi). When it is below the setpoint like when starting or ignition is keyed on but engine is not running, the switch...

    Mercruiser 4.3 oil gauge mystery

    How did you test them? Would think you need to apply different pressures and see if the ohms change , dont know the ohm range off hand but usually if you ground tge sensor wire gauge should peg one way or other

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    If there is fuel present in the tube your mechanical fuel pump needs replacement. as mentioned this will be pushing fuel from a ruptured fuel pump diaphragm into the carb bores… better than the fuel going into the bilge though. Get a marine replacement pump and you should be good. may be other...

    Video: What The Heck is This?? - 1999 VOLVO 4.3 GL - 2 bbl Holley Carbureted, ETS ignition

    If you think the fuel lines look bad from the outside I would replace them could be degraded on inside? Can you rig up a fuel pressure gauge to watch while running

    Mercruiser 4.3 oil gauge mystery

    I think the alarm switch (which sounds on start) and switch for fuel pump are two different switches.

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    Agreed- had a float with a small split on it couldn't tell it was leaking ... To OP -These could be your issues Float being gas logged or hanging up needle and seat too high fuel pressure I assume you have a mechanical fuel pump - there should be a clear tube coming of it and going to carb...

    Dam it! Wont Idle

    Heres a video on it or the first one in a series showing rebuild. usually if idle circuit is plugged it will idle low or wont idle… make sure the linakge is not hanging up. I would disconnect the throttle linakge and make sure throttle plates are returning against the idle speed screw, look...

    I think last time i bought a bosch gauge at the autoparts store it was like $25 https://shop.advanceautoparts.com/p/bosch-gauges-style-line-2-mechanical-oil-pressure-gauge-white-face-fst-8206/10717222-P fittings on the block are 1/8” NPT…

    Mercruiser 4.3 oil gauge mystery

    Exactly T it in by the sender and you can run it and see . Hot if you have 10 psi for every 1000 rpm you will be fine. to the OP did the oil get fuel contamination from running rich?

    Alpha 1 gen 1 water pump

    Would also recommend the oem parts as well. It’s been a few years, but last time I ran a Sierra impeller while it worked fine. When I changed it out, it seem to have a lot more wear on it than an OEM impeller of similar age. This is completely anecdotal, but it was my feeling that the sierra...

    Stalling and Starting problems

    If it is running with the key off there is a problem and someone may have futzed with the factory wiring. The pump gets power i think off the starter during cranking , then off the ignition circuit via an oil pressure switch during running. oil pressure switch is there to prevent pump from...
