aftermarket mechanical fuel pump

Is there supposed to be a direct swap aftermarket mechanical fuel pump for the Mercruiser serpentine driven fuel pump system? I bought a Holley marine not thinking anything of it, and the arms are clearly different? Am I just supposed to modify the arm? Or is there a different pump to get?

Thanks,.

I know of, and used one, for the v belt setups.

Search including the term airtex and it should show up

Take the bottom half off the Holley and attach it to the stock mercruiser top.

I actually thought about doing that. Is that actually what you're supposed to do?

I've been doing some more searching - is the Mercruiser 454 pump actually a SBC pump? The arms look similar to that of a SBC fuel pump.

Thanks!

Nope, I just replaced both my mechanical fuel pumps on both boats with Airtex. Airtex makes the Merc pump it's just not painted black. Model 60932

so is there any way to get the Holley 110 GPH fuel pump to work or, if you want something other than a stock replacement do you have to go with electric?

Thanks again.

60932 is the pump you want.

??? Like I said before take the 6 screws out and swap the lower halves. Done

I bought a Carter from Summit Racing for my 350 Mercruiser. It had a different arm, but bolted right on and my engine runs flawlessly. I will be putting it in the water tomorrow, I'll let you know how it runs.

Alright, I didn't know if that was really a solution or not. Sounds good to me.

Are the specs the same between Airtex and Merc? I just replaced my pumps with Merc pumps earlier this season. The Airtex pumps say that they have been fitted with components compatible with multi-rich fuels. Just wondering if my new Merc pumps will survive with all the ethanol we're getting now.

Don't see an issue with the fuels, Merc doesn't make the fuel pump, Airtex makes it for them from what I have been able to determine. You use to see Airtex embossed on the side of the Merc pump years ago

Merc doesn't make a whole lot of things, like starters, fuel injectors, carbs, distributers, etc

That's correct, have used plenty of them costly! but; 100 % rebuildable.

08-15-2014 01:07 PM

I understand that Merc doesn't make the pump. What I'm asking about are the specs.

Like already said CV Products has "THE" pump, if you dont mind paying for it. I wouldnt trade mine for anything, work flawless, rebuildable, and awesome looking all billet construction.

I had the CV on my 557, flawless. Think it was model 2640 (?) And as MER mentions, they are rebuildable when/if that time comes.

You can replace the lower half, but the diaphragm and springs stay with the top half. The shaft that holds the diaphragm plate and springs in there looks to be riveted in place.

Where did you buy the Model 60932 pump? I didn't see that pump listed in the usual places (and those recommended by the Airtex website)?

I just googled airtex 60932 and looked for the listings, then bought the one who was cheapest. This time I picked them up from Amazon for 55.35 each including shipping.

PowerAddict

FYI, the 60932 is out of stock, pretty much everywhere. 2 week delay.

Can someone explain how this works?

Indicate they can ship but don't know of a back log, not listed

I used the Carter and it works perfectly.

Thanks for the response guys. Unfortunately when I went to check out my shopping cart, Autozone said that they no longer had that part. Amazon is saying 1 to 2 months in the one listing. Still this is great to know that there's another less expensive source given how the diaphrams leak. For me, the issue with the Eikert and CP upgrade part is that I'd still be reusing the upper half of the pump that fails!

Do you have a part number on the Carter pump?

Thanks.
