Fuel pump failure!

Post by offcenter »



Gentlemen,
The fuel pump on my '76 is pissing fuel out of the weep hole in the side of the casing.
What is the latest consensus of how best to fix this?
I found several older threads about rebuilding the original pump or replacing it with
an electric one. But most of them are from several years ago.
Has anyone come up with a newer better idea to repair or replace my pump?

Or...Where is the best place to buy a OEM replacement pump?
Thanks guys.

Not much can go wrong with the pump other than the rubber leaking.

Some have replaced it with electrics but you have to make sure you get one that pumps the right amount of fuel and has a tip over switch.

I bought a new pump from EBay and never ended up using it.

They are still available on EBay, OEM for like $85.

If you need one I can sell you the one I have for $50 shipped but see if you can repair your's first.

Ok guys, Snobrdr wasn't able to help me.
Anyone else have a fuel pump sitting around that
they don't need and would like to sell?

You could just buy a piece of Viton to cut as a new diaphragm, then take the pump apart and replace the diaphragm. That's usually the part that fails, and if it is leaking fuel, that's almost certainly what has failed.

Wingadmin, I read the entire thread about that, and I thought about doing it.
But the part about drilling and tapping that tiny piece in the middle
gets me. I'm more of a woodworking kind of guy. I don't really have
the proper tools for that. And while it might work, it also might
not.
So I think I'd rather just buy a new pump and install it. After all,
that pump is 40 years old and has 75,000 miles on it.
I'm just hoping that maybe someone else has one that they
want to sell before I spend $85 on a new one.
Snobrdr thought he had one, but he was mistaken.
It was nice of him to try though.

I have some used pumps with good rubber..$48 with shipping. But remember they are 30 years or so old too. Still working w/o leaks. Or I can send you one drilled out already and ready for new rubber..same price.

Rbgerson, thanks for the offer.
But my wife got tired of me grumping about the whole
fuel pump thing, so she went and ordered me a new
one off of Ebay when I wasn't looking.
Can't complain about a woman like that.

Hi all

I have a fuel pump problem, made worse by the fact that I am in Mexico at the moment. About a week ago The pump failed but it happened near a quad mechanic. He took the top end off the pump and cleaned the valves up, put it together again and it worked perfectly. Yesterday evening it happened again. I copied his work and it ran for 30 minutes before giving up and now I can't get it to work at all. Finally got recovery to a hotel we had booked in Teothuacan. I am looking for a mechanic here but... any ideas?

I've never had an 1100, but here's a link about generic pumps. I'd do that if I were in your situation.

If you're really stuck, you could jury-rig a tank (jerry can?) strapped to your trunk, and run a hose from that to the fuel pump input (assuming it will flow fuel when under pressure). You could then just gravity feed the carbs. If not, you could try hooking it directly to the output hose from the fuel pump, to try to gravity feed the carbs. Hokey, but it could get you home. Carbs don't need a lot of pressure, they will gravity feed just fine.

I have a feeling that your pump has packed it in completely, and the "30 minutes it ran" it was actually gravity feeding from the upper part of the fuel tank. If the fuel tank is full, The top of the fuel is higher than the carbs, and it will gravity feed. After half an hour or so, the level of fuel drops below the carbs, and it no longer gravity feeds, so the engine quits.

Thanks guys...the jerry can idea would look pretty crazy! I solved...I hope ...the problem. I agree that the pump has probably given up the ghost totally, and yes, the tank was full when this happened.
I looked at the electric pump workaround on Goldwing facts. Thought I may as well try.
So I managed, with help from a kind local car mech and an even kinder taxi driver, to get into town and locate an electric, low pressure fuel pump. Linked it all in and hey presto, she lives! Of course, it leaked, so I then had to find some plumbers tape, thanks to the hotel caretaker, take it all apart, tape the threads, and redo it all.
It's not pretty but as long as it works I'm happy. We are planning to carry on our trip south, into Guatemala and Belize, then back up through Mexico to the USA.
I hope I don't need more help, but it's good to know you guys are out there. :)

Wow DiverRobin, sounds like an epic and beautiful trip. The Yucatan is a place on my bucket list so it would be great to hear about Guatemala and Belize.

We are in Guatemala now, at Lake Atitlan. The electric pump has been working great. Actually the bike seems to run better from cold, and smoother at low revs. So maybe the old pump was on its way out for some time?

I would like to post details of the trip...how do I do that here?

Thanks again for all the support...this really is the best group.

I mean to position it better when I get the chance...I am concerned it may get a bit hot where it is.And the cable ties are none too pretty!

As long as it's functional,all good.You can probably sheild it with some aluminum tape or foil to keep the more direct heat off it, probably wouldn't completely wrap it,may vapor lock,but at least stop the engine heat from direct contact.Just a thought,enjoy your trip and stay safe!

Good idea about the aluminium foil, jamie f. I was looking to move it off the engine completely but that would be a lot simpler.
And I will get sometrip report up very soon, thanks WingAdmin
