89 5.0 fuel pump

[Travis71]

Trying to get boat started and am not getting fuel to carb. I even tried attaching a short piece of fuel line and stuck it in a gas can. Held my thumb over the end of it while cranking, couldn't feel any suction. Can the fuel pump be rebuilt or is it better to just buy a new one?

Original part number is 985723, which is no longer being made. I am having a hard time finding a direct cross reference with that number to another manufacturer. What's the best way to make sure I get the right part?

On a side note, I tried putting gas directly into carb and spraying carb cleaner and I still couldn't get it to start. I filed the points and checked dwell, 30.4 (manual says 29 +/- 2). Getting spark using inline spark tester. What else could be going on here?

I would buy another, search on the part number and it will show up

Carb cleaner is not that flammable. If gas won't fire then either spark is not making it to the plugs or its bad gas

the original pump is a carter. most marine pumps are carters.

what is your compression? should be about 140-150 psi per cylinder.

I have a Carter on my 2.3 and purchased one from Summit. I know it's a different engine but might be a place to start.

I don't know compression numbers. I don't have the tool to test it.

You are correct, it is a carter. Has 60651 stamped on the flange where it bolts to engine. I can't find a direct cross reference to this number or the original part number. I managed to find a carter marine fuel pump (M60389) and a precision fuel pump at OReilly that look the same as the original, except the inlet/outlet holes don't look to be in the same spot. Sierra Marine has one that says it fits Ford 302, 18-7267, but it looks very different.

Either spend the $20 and buy ine from amazon, or borrow one from the closest FLAPS (Friendly Local Auto Parts Store)

Got a compression gauge from Amazon. Seven cylinders were 125. One cylinder was 115. I had already pulled all of the plugs so I checked each cylinder with all the plugs out, that shouldn't affect the readings should it?

Those numbers are lower than what you mentioned, but I put the plugs back in and the new fuel pump on and it is running fine. Or at least same as before.

the motor is tired and while it runs, you only have about 80% of its original power. if the compression gets lower than 120psi, time for a rebuild

Just in case someone else goes looking for a fuel pump and comes across this post:

I found a Carter 60389 at Walmart.com of all places. $63 delivered to my door. Almost identical to the old one except the inlet and outlet were in a different position. I took it apart and rotated bottom piece so that the original steel line supplying the carb lined up. Then I got some fuel line and a brass hose barb from NAPA to make the connection from the fuel pump to the fuel filter.

Thanks for closing the loop on this.

yes, many times you need to clock the housing as you have done.

Make sure to use blue loctite on the screws
