    Black Scorpion Mag Mpi fuel pressure

    That inside the fuel tank? Fuel pickup tube in gas tank delaminated? Was the fitting blocked too at all? Some low psi pumps have a screen in the front side of them that could collect debris so if the issue continues you may need to inspect that area too but seems less likely at this point as you...

    What year model is my mercruiser 3.0?

    0F880027 seems to come up as an 1996 3.0LX [ALPHA] Model number 430L100JS. To find parts always use the serail number of anyone of those three depending on what you're looking for as the year doesn't mean as much such as your example. Here's a parts guide for your engine model...

    Hesitation/RPM Hunting on 496 Mag HO

    Maybe run the engine at night and look for a light show under the brackets/bolts, by the valve covers, etc. from the spark plug wires as these engines tend to that from bad wires leaking spark. If you didn't have the injectors removed and professionally cleaned and evaluated from the paint...

    Black Scorpion Mag Mpi fuel pressure

    You're in spec for now... If possible, go run the boat with the fuel gauge connected ... Also suggest bringing an external fuel tank and fuel hose to bypass the boat tank and see if it runs normal...Also open the boat fuel filler cap to vent the boat tank to see if it helps any...50/50% chance...

    Lets go back, What is/does the PSI do when you remove the vacuum line at idle? You're at 26 right now so it ought to jump up to 30ish psi spec when you remove the line...Need to recheck that test. Next this is where you'd need to be in the water with the fuel tester gauge connected to see if...

When all is working normal the fuel pressure should go up to the regulator specification when you remove the vacuum line...
