1963 Merc 110 Fuel Pump.

[BonePile]

I'm having a hard time finding a fuel pump assembly for my 110 merc of the same year. A lot of parts are obsolete for this model year. Is there anyway to retrofit a modern fuel pump into it?

Lots of things you could do.--Look into cutting a diaphragm from say a Johnson fuel pump.--Cheapest / simplest fix I would say.----Very little goes wrong with those pumps.---I own some of those white Mercury motors if you question doing this.

BonePile Welcome aboard.

Moved this out of an 11 year old thread. Please read the Help Tip on top of the page. Few of us go back to look at the old threads.


Now - Do you need a complete fuel pump or a rebuild kit? Is this your fuel pump? http://www.iboats.com/Fuel-Pump-Asse...iew_id.1702046

To be more specific (not sure why I didn't mention it), the check valve seems to be missing from my fuel pump. We have already replaced the diaphragm in the fuel pump. The exact check valve replacement seems to be obsolete. I've checked oldmerc.com and other parts site for older mercurys. Maybe a check valve from another model may fit and be an adequate replacement?

Look for Quicksilver 21-30430A 2. It's the check valve kit and the valves only come with gaskets and a diaphragm. Save the extra parts for the next diaphragm change.

I'll try that. I can't understand why they would come up as obsolete for the oldmerc.com site and others. Thank you!

Before you order - Does your fuel pump look like the one on the parts drawing in post # 3?

I may have grabbed the wrong kit. Item 2 in the drawing is the check valve and they are in the inlet and outlet fittings.

 

[BonePile]

My pump does look like the one in post three. I believe item 2 is what I'm looking for. So that part won't be in the kit mentioned before?

Can you post a picture of the check valve?

 

[GA_Boater]

I did give the wrong part number.

That pump has what I'll call non-standard Mercury check valves. As I said, the valves fit the intake and output fittings instead of being inside the the pump. I found the correct valves last night and need to find them again.

 

[GA_Boater]

The check valves only comes in a kit as far as I can tell. The valves are not the regular "top hat" check valves.

Search Ebay for Quicksilver 21-22974A 2, the kit number, if this doesn't work - http://www.ebay.com/sch/i.html?_fro...+3.TRS0&_nkw=quicksilver+21-22974A+3&_sacat=0

The check valves look like this. Some pics show the valves nested together.

 

[BonePile]

Thanks for the help. Hopefully these will work. Of course winter decided to come back for more in upstate NY, so getting the boats out early doesnt seem wise right now.

If I was stuck for parts on that motor I would fit a reliable pump off a 6 / 7.5 / 8 / 9.9 / 15 hp Johnson / Evinrude.-------Parts will be available for a long time.

Trying to figure out how to install the check valves. Old ones were in the pump but were missing the white seal located in the center of what would be the opening. Removed them and now need to figure out how to install the new ones.

See if this method matches your pump type.
