Where are the rest of the parts?
by Wes from Debary, Florida on July 05, 2013
When I ordered this fuel pump rebuild kit, I wrongly thought it was a complete kit. There are no diaphragms in this kit. My fuel pump has three inside the fuel pump. Also, the gasket between the fuel pump and the cylinder head was not supplied with the kit. When rebuilding a fuel pump, it is expected you would be able to rebuild it completely.The item title is "Fuel pump kit" . More correctly, it should be labeled "A few parts that leave an incomplete job" Does anyone know where I can find the diaphragms and gasket for my 120 hp Force outboard?

Fine product, very poor support
by Joshua from Fitchburg, Wisconsin on July 06, 2016
I ordered this part along with a manual about a week before a fishing trip. The manual arrived in perfect condition, but the part was not in the package. I submitted a request for assistance online which was never, ever replied to. I further called and was told it was too late in the day and someone would get back to me the day after nobody called or emailed. So I ordered the part again with urgent shipping and got it just in time to do the repairs needed, but I had to pay for it TWICE and expedited shipping TWICE and I still haven't heard from iboats about it. I'll look elsewhere for parts in the future.

diaphram fuel pump 18-7817-sierra
by John from Deerfield Beach, Florida on May 25, 2015
i found you out from a u tube video on how to rebuild my fuel pump . everything was alright and i was able to complete the job myself which saved me allot of money. my only problem was with the "I" gasket shown on the bottom of your pic of parts shown to my left. As i was installing it somehow it fell and when i picked it up i noticed it was torn.It was made of some type felt like material ,which to me, seemed kind of flimsy for a gasket. my old one seemed intact and made of a rubber like material that was obviously much stronger. This also gave me some doubt about the overall integrity of the product.However,my boat is running fine and thank you for making this product available. John A. Ladkani

Perfect
by Noel from Orlando, Florida on July 23, 2012
Rebuilt the fuel pump on my Mercury 40 Classic with this kit. It is a perfect replacment and match with quality parts. I even think the material used for the diaphragms are even better then OEM. Gaskets are high quality. No problems with the install, however, you will probably want to refer to a maintenance manual as the kit does not come with any instructions. Pretty straight forward nevertheless as long as you realize that you have to break off the little plastic pins on the leaf valve retainers and then press them back into the retainers to expand the retainers and lock thim in place.

Damaged
by Milton from Mcgaheysville, Virginia on June 16, 2012
Well Saturday is here, time to rebuild my fuel pump on my outboard. Everything out of the way, pump is off, disassemble, start rebuild, comes to a halt, one of the rubber diaphragms has 2 pin holes in it, of course I am told to call Sierra, if they say its bad then to call iboats and return for replacement. For a 12.00 kit, think not, waste of time ordered new one from someone else

Wrong kit.
by Robert from San Gabriel, California on March 31, 2012
I ordered two different kits. Not sure which one was for my fuel pump I ordered them both to be safe. The one kit had all the parts I needed so I returned the other one and will order another one of the same that I used as a spare.(JUST IN CASE THE PROBLEM SHOULD ARISE AGAIN)Ha ha. I haven't had the boat on the water yet 'cause it's needing an advanced oil injector pump. She was neglected by her previous owner. As For my satisfaction with iboats.com,I am COMPLETELY SATISFIED!!

by Robert from San Gabriel, California on March 31, 2012
I ordered two different kits one of which had all of the parts I needed but I wasn't sure according to the picture foe certain parts so I ordered the other kit that pictured the parts that I would need to completely rebuild my fuel pump.Upon returning the kit I didn't use,I will order the first kit to have as a spare at hand.My satisfaction really wasn't thumbs down, what I ment by that is explained above. Completely satisfied R. Crouse.

Fuel Pump Kit
by Deborah from Cleveland, Tennessee on September 17, 2011
Diaphragm and seals were all bad on my fuel pump... motor having a heck of a time trying to plane out and reving/jerking. Wouldn't idle. Fuel pump wasn't having enough pressure to suck the fuel through. Got this for $11 and rebuilt the pump (which is nothing to do) hooked up the lines to the pump and mounted it back to the motor. Took it out and the motor ran as good as new. Beats paying alot more for a brand new fuel pump all together. BTW, this is the only place online I could find this particular fuel pump kit, so thanks iboats...

A:

A:
No this will not work. This only works with 706/707 HA, HC, HD, HE Chrysler models.


Q:
Is this the right kit for my 1995 70 hp force ??
A:
Looks like it should be 18-7817. Serial # E000001-E065371 use 18-7806-1. 1995 should have a serial range after that though so verify serial number. If you have further questions contact us at the number at the top of the page.

This fits 1995 force 120hp?
A:
No, you will need part number 18-7817.


Q:
Will this work for a 105hp Chrysler outboard?
A:
We will need the engine model number to confirm parts for a Chrysler outboard.


Q:
1992 Force 70 Model 708F92A will 18-7817 work?
A:
Yes 18-7817 should work for your application.

A:
Yes this will work for your motor.


Q:
I have a 1996 force 40 ELPT i wonder if this will also work?
A:
Yes this will work for your motor application.


Q:
Will this work on a 1991 Force 50hp outboard?
A:
No you need part number 18-7806-1.


Q:
Where can i find the installation instructions?
A:
You will need to refer to a repair manual, Sierra does not provide instructions. You can also contact a local technician from our professional installation tab.


Q:
I hope this is the right part ? hope its a sera # that is tthe merc # for the 21-857005a1?
A:
Well it cross references with 21-857005A1 if that's what you're asking. So if the OEM number to your fuel pump kit was 21-857005A1 then this will work.


Q:
