NAPA (Mustang) fuel pump for K11 fuel pump

From: BillZ <BilZ@longride.net>
Mine died a sudden death somewhere around 70k (93 K11rs, not that that should make a difference) and I am now the proud owner of a NAPA pump for a 4 cyl Mustang, $80 and doing fine.

If you want to add to the fuel pump reference of mine, the NAPA part # is P74095 for the pump I installed. The NAPA pump now has over 30k on it with no problems.

Here's the foam sleeve adapter for those 37mm pumps to run in the 43mm mount.

Mate just received 3 VDO fuel pumps Part No A2C 59510945 for a discounted price of $124.00 Au. The pumps are 51mm diameter so will require either a sleeve of shrink wrap or stainless cable ties to make it secure. The electrical connectors do not need modification, and it came with two different filter screens which should be compatible with the K tank. They are available on Ebay but at $75.00 Au with screens $60.00 without screens.

I haven't needed to replace mine yet but it was mentioned in another thread (regarding BMW dealer prices going up).

Using an automotive aftermarket fuel pump has been mentioned in places like this:

https://www.motobrick.com/index.php?topic=2058.0

I got curious about local prices so I looked up a '90 Lincoln Continental (3.8L V6, the only engine offered during that period) and found their Carquest brand pump for $63.99

http://shop.advanceautoparts.com/p/carquest-electric-fuel-pump-e2042/3140091-P?navigationPath=L1*14932%7CL2*14986%7CL3*15378

NAPA carries one for $59.40, if you trust using NAPA over Advance. Seems they sell Airtex pumps with lifetime warranties.

https://www.napaonline.com/en/p/AFPE2042

In stock at my local store and with a lifetime warranty. The dealer ain't going to give you that. Nice knowing that if you're on the road and need one you can walk into most any auto parts store and pick one up.

I also checked my favorite online parts store, Rockauto.com, also using a '90 Continental:

http://www.rockauto.com/en/catalog/lincoln,1990,continental,3.8l+232cid+v6,1187995,fuel+&+air,fuel+pump,6256

Offering a wide array of choices, their cheapest was $15.84. That's cheap enough to toss one in your tail cowl just in case.

$38.79 gets you a Carter with a lifetime warranty if you want to pay more for supposed "quality." Hell the TYC for $18.20 has a lifetime warranty too.

$65.79 will get you a Denso.

And to refresh our minds, BMW Motorcycles of Grand Rapids lists a fuel pump for my '87 K75 for $475.46.

Hi, check eBay seller highflowfuel (39801) $69. I installed one in my 96 K1100RS. Slight modification with a hose clamp but fits in existing pump fixture. Comes with a strainer. Installed last year still running fine.

I bought one of those $20 BMW K75 fuel pumps found on eBay and carry it in my tail cowl.  I can't say how well it works, but I operate on the principal that when you carry a spare, that part will never fail.  So far it has worked.

The only issue with the replacement is that it does not use the ring terminals found on the OEM pump, but rather 1/4" spade terminals.  One of these days I have to get ambitious and set up the in tank wiring to expedite the change over.

[Martin]

For Ozinians I'm actually thinking of getting one of these and putting my spare original one in the tail as a just in case. https://www.aliexpress.com/item/for-BMW-K-Ducati-K75-K100-K1100-K1-1983-1997-BOSCH-16121461576-16121460452-0580-463-999/32784411992.html? Won't be happening for a while though as I have other projects going. I am also trying to find reports on these pumps.

I saved this vendor in case I ever need one, thanks for the other sources http://www.ebay.com/itm/331387290009?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Are the electrical connections the same?

Could you elaborate on the "slight modification with hose clamp"?

Would you consider the whine from the fuel pump at an acceptable level? Quiet, slight, loud as hell at a stop light?

Thanks

[bmwpyro]

not sure if i have the same exact pump as motomans but its the same price as the model fuel pump the bike came with .. This one... https://goo.gl/or0DXK or https://ebay.to/2IjQV08 *
electrical are same. not sure what he meant by the hose clamp. mine used all stock.

the only thing creative is the way its wedged/held in the old oem fuel pump can with old fuel hoses cut open.

at idle i would say between quiet and slight. more on the quiet, with fuel low indicator on.

depending on how young your ears are, YMMV.

*goo.gl will phase out their links next year Mar.2019

[ckp]

That's the pump I looked at.
My ears are not the best from spending my life around air tools and loud music. My pump sounds like a car with blower whine or gear drive when I stop, with my full face helmet on. I'm going to replace my fuel filter, since it's cheap enough and never been replaced during my ownership. My gas tank seal leaked water in last year and I think I checked the filter when I had the the tank off, can't remember. I ran water through the pump before I realized why it wouldn't start. Maybe it got noisier due to the intrusion. It doesn't seem likely, but it's certainly possible. My pump has always been noisy. I can live with an acceptable amount of noise, but the way it is now, I cannot see the first owner making it a few days without returning the bike. Of course, it is 2 decades older.

I replaced my pump because the usual whine noise had increased. I pulled the pump and discover the strainer at the inlet of the pump had started to disintegrate. The bike is a 96 K1100RS with 90,000km.
I tested the old pump and it was fine but since I had the new pump and strainer I installed it. The new pump was missing a ridge on the casting to retain it in the holder. With the hose clamp on the new pump it was a tight fit. That was 5000km ago...no problems since.

Beat me to it! 

When traveling, I keep the spare in my iconic 22L top case.

Thanks. I will inspect when I change the filter. The 2 previous owners took meticulous care of the bike, so I will dig through the receipts and see if any related items have been addressed. My bike has 43,xxx miles on it.

Greetings,
I will keep that in mind. I have run below a 1/4 tank more than once. I usually start looking for a gas station after 150-170 miles if I'm not in the boonies. There is ethanol in all the fuel I have ever put in anything I own. The only alternative is race gas. There is no way around it at the gas station.

[BrickMW]

If you ride your bike plenty and don't leave gasohol to deteriorate in the tank for weeks at a time, 10% ethanol fuel isn't a problem.

[The Mighty Gryphon]

I start running the no corn good stuff in mid to late October, through the winter and up until the 1st of May.  Rest of the year fuel only sits in the tank for a week or less so I don't get too fussy about what I put in there. 

Touring, when a tank only lasts 3 hours, I run whatever they're selling and won't think twice about it.

Around December, when I am pretty sure I'll be getting snowed in for a couple months, I start putting a little Sta-Bil in the tank and running it through for a few minutes.

[BrickMW]

100% gryph.. my first "won't start" adventure came down to 14 day old 87 Oct w/corn juice. Since then I only used non-ethanol unless like you said, I know it will be empty soon.. (long hauls, good weather, etc..)

We are blessed in this area with many options close by for "pure" gas.. I hope it's going to stay that way, and continue to increase in choices.

This might be a little late, but I hope I am not hijacking this thread.

I received my fuel filter the other day and proceeded with the removal of the in tank fuel supply.

This HAS to be the easiest fuel pump removal I have ever attempted.
1. Place a soft cloth on the tank.
2. Remove the gas cap assembly and set aside.
3. Loosen the clamp on the short hose of the fuel filter going to the in tank pipe and pull hose off of the pipe.
4. Squeeze one side of the plastic retainer with your thumb and tilt the pump.
5. Squeeze the other side with your finger and the pump is loose.
6. Carefully wrangle the filter and pump (wiring still connected) out of the tank and set on soft cloth. Let the filter drain back into the tank.
7. Remove the 7mm and 8mm nuts for the wiring and place assembly on workplace.

I blew through the filter. It seemed okay, yet wasn't as easy as the brand new one. I thought it could be because it was still wet. I decided to cut it open and have a peak at it. I found it collapsing. I believe the fuel pump was trying to suck the filter through it's tiny hole and thus collapsed the paper element.(Edit: That doesn't make sense, it's on the exit side of the pump). The fuel pump sock looks fine, other than being discolored. I will replace it.

If anybody has replaced the sock with an Autozone or the like part, could you tell me the part number? I have done no searching or researching as of yet. It looks like any other fuel sock I have replaced. I think I have one with the metal "clamp" in the middle instead of on the end. Is this significant?

Thanks

This is your chance to start researching, ckp. Go to the Repair Guidance section's Master Index and look in its Alternative Parts section.
