OMC Fuel Pump - Replacement pump Or Rebuild Kit

[KM7]

Help! Replacing a fuel pump on an 91 5.8:L Ford with a 4 barrel. I found what should have been the matching part but the ports into and out of the pump do not line up with the original. They will not line up with the hard lines that come from the filter and to the carburetor.

Engine 584APLRGD , Fuel pump per the Crowley Marine site 3854053 or 0987024 .

I found the pump here: https://www.offshoremarineparts.com/62-32-053.html

I do see that the replacement pump looks just like the picture on the Crowley site item #10 Note the port positions.

The problem is that my old pump does not have the port the same as even the crowley picture.

See pictures. This is a 91 engine on a 92 boat but I think everything is stock. Why is my pump different???

I was even hoping that I could remove the lower section of the new pump, and rotate it 1 screw hole and put it back. But that would not line up either. If you look closely at the screw holes you can see that.

What is the fuel pump part number for my pump - It does not look like the picture.

Do I have a fuel pump off a different engine?

91 5.8 L Ford model 584APLRGD. The OEM fuel pump per the Crowley Marine site is 3854053 or 0987024.

BUT the picture does not match my pump, See attached. The picture shows the ports coming out straight, Mine come out at 90 deg??

What have I got and what is the part number for mine.

Thank you very much.

Need rebuild kit for a fuel pump on a Ford motor on an OMC

Where can I find a rebuild kit for a fuel pump on a 91 5.8 L ford motor. The motor model is 584APLRGD.

The fuel pump part number is (new) 3854053. (old) 0987024.

Thank you

simply clock the new pump and go boating. just pull the 6 screws and clock the diaphragm part.

At Scott. I thought about that but I need the clock it 90 deg and there are 6 bolts so I could rotate 1/6 or 2/6 of 360. In other words, 60 deg or 120 deg but not 90 deg!! The IN and OUT are hard lines so it has top be close to exact.

Any idea why my pump does not look like the on in all the diagrams?

I’m not sure that is the right pump. Look at your old pump and see if it has a Carter part number o it. Many Carter mechanical fuel pumps are still available you just need the number. I got a Sierra r placement for my old Carter and it lined up perfect. You can also go on to Carters on line catalog and see if you can find it there. Once you have the # you can order Carter pumps from Jegs and Summit Racing.

this is the only one I found on Carter's website for the Ford 5.0 or 5.8. Same thing you got? If you can't clock it to make the hard lines line up as you say then if you can get one to line up, replace the other line with a flex line with the same fittings, Sierra makes one.

It was a custom OMC only use pump.... Without any sales it probably was dropped from the carter catalog

you could pull the diaphragm and checks from the new pump and install in the old pump

or bend up new lines (3/8 brake lines)

I bought a rebuild kit from Then and Now http://www.then-now-auto.com/fuel-pumps/

$53 + $11 shipping. Cheaper than the new pump ($158 + tax and shipping = $172)

I will post how it goes.

Got the fuel pump rebuilt. Works great and was 1/3rd the cost of a whole new pump. I did carefully follow their instructions to compress the diaphragm spring while I tightened the 6 screws holding the 2 halves together. I did that by wrapping string around one of the screws and around a short piece of pipe with a lip in it that I hooked over the actuation lever. I could wrap the string around a few times then compress the spring and tighten the string. That held the spring compressed while I tightened all the screws.

The reason that you compress the spring first is so the diaphragm is pulled into the most "flexed" position. If you don't do that the diaphragm is being *stretched* each time the pump strokes and that will cause the diaphragm to fail much sooner.
