'91 GL1500 fuel pump

Postby Sidcar » Fri Jul 13, 2012 7:57 am



Hi folks,
I recomissioning a GL1500 that has been standing in a barn for many years and unfortunately the fuel pump does not work. I've taken it of the bike and tried it on a battery and it is dead. Having clocked the extortionate :o price of a new one I wonder if anyone knows a cheaper alternative.

Regards

Sid

There is a pump made for a car that is much cheaper.
Someone on this site replaced theirs but I have no idea exactly what it came off of.
I hope somebody will chime in with the details.

Have you taken the pump apart to see if it can be repaired?

I've been told I need a pump for a Honda Prelude,86-89 carb model. I'm trying to find a picture of one to see if it looks like mine.
The inside of the tank is badly rusted so I think that will have to go as well.
I'll get it on the road one day but as it's still pouring with rain what's the rush.

I'm not sure.I think the prelude pump is external.we use it on the 1200. Be sure it's made to go inside the tank.More research needed.
There are posts about de-rusting a tank too.

I would try a fuel pump from a Honda vlx 600 motorcycle It fits external from the tank.

With nothing more on my mind than saving myself a few hard earned quid, and having nothing to loose, I dropped the pump into a pot of brake cleaner overnight, a really good solvent. In the morning I blasted it out with compressed air and then tried to turn the impeller of the pump. It moved slightly so, as this was in an aerosol, I sprayed it with electrical contact cleaner. Eventually I got it to rotate and a bit more cleaner got it moving reasonably freely. I then connect a battery and hurrah it worked.
Will it be good enough to pump petrol? I'll put back in the tank tomorrow and find out.
If it doesn't I've been told an ST1100 pump, fitted to my bracket, will do the job.

Tell ya what I'd do.
Safely hook it up after it's really clean and let it run in a small can of diesel fuel(submersed)
Don't pump it out,just let it lay in there and run and circulate.
The diesel fuel will help clean it while keeping it lubed.
You could run it in there for several hours and then test it for pressure and volume in regular gas to see if its working OK.

In the absence of any diesel I put the pump back in the tank and pressed the starter. It fired up a treat. I know the pump is working well because I now have petrol pouring out of the carb' overflow pipes. So onto the next job clean out the carb's. When their done I can run it properly and see how the pump bears up. Did I say I was changing the tank as well. The present on is badly rusted inside so I've bought an as new one of ebay. Fitting it doesn't look a quick job.

Your gonna love pulling the carbs.My first time...I'd never said "you got to be kidding" so many times.it took 3 hours.now I can pull them in just under 2.oh by the way,you do have to drain the radiator.get a pair of 11" needle nose pliers.preferably one with a angled tip and a 18" Phillips to get them loose.

Bit of a sod having to drain the radiator I've only just refilled it with fresh anti-freeze. I'm told the cost of replacing the piston/diaphragms is equal to the GNP of a small nation. This true? I can't find them mentioned on Ebay.

Keep the antifreeze clean and re-use it.
The only reason to replace the slides/diaphragm is if they have a hole or tear in them.
If they do,research just replacing them and not the whole thing. Its aftermarket obviously.
The last ones I saw were almost $200 each USA.
In a pinch, just to get by,if there is a hole one could use a piece of nitrile rubber glove and Gorilla glue and clamp it into a "patch".This really does work but you HAVE to use nitrile and Gorilla glue. Nothing else Ive come across will withstand the fuel.

I've done so much with so little...I can now do anything with nothing :D

I have a 1996 GL1500 and just went through putting on new fuel pump from the scenerio of the honda prelude.. The bike had been sitting for about 6 years and the fuel pump was rusted from the old fuel. Didn't bother to soak and clean old one just to have it be to weak after all that. Now that I have the fuel pump on it, it does start but now I have fuel coming from all kind of tubes under the bike. Does anyone know if the pump needs to be adjusted or anything or if I have some other problem? I have not put the breather back on yet, but I don't recall unhooking any fuel lines when I took it off. There are 2 small line under bike close to brake peddle fuel is pouring out of one of them, and also in the front under the radiator area. It is definitely pumping fuel now, but just to much... Any help would be great.

If you put in the one from a fuel injected car it puts out 70+ psi and will overwhelm the floats. Also the lower psi car fuel pump puts out some where around 20 gpm and will be short lived in your goldwing. It will over heat with low fuel in the tank. Good luck

Has anyone considered using an external fuel pump? There are lots of options for external, electric fuel pumps and it wouldn't be so difficult to install a fuel pressure regulator with such a critter...
Keep the rubber side down.

I've stripped and cleaned the carbs. Had hell of a game actually getting them off the bike, the rubber sleeves have gone quite hard. The l/hand carb float was stuck to the floor of the chamber hence the fuel leak.In fact the left one had a lot of "shelac" and green corrosion in it which resisted heavy applications of brake and carb cleaner. Eventually I put it in an Ultrasonic cleaner for about 15 minutes and that cleaned it up a treat. The right one was like new inside and cleaned out easily. The diaphragms were quite good, no holes. Just got to coax the carb unit back onto the bike.

I replaced my fuel pump from one that fits, 88 Honda Accord DX and it also fits the 92 Honda Prelude that's carbureted. I am now having a problem with the line being submersed getting eaten alive by ethanol. Any way I went to a boat shop bought marine fuel line and in less than 36 hours it's been eaten from the outside and the pump just keeps pumping back into the tank, no fuel coming up to filter.I was told by the boat shop I shouldn't need ethanol additive and I do run 93 octane. Any suggestions? This is a 93 1500 that had sat for five years I had it running in two days and no problems until now, 10,000 miles later.

I replete you are wasting your time using a Honda car fuel pump they will over heat and have a very short life span but its your money. Honda makes a motorcycle fuel pump that is external from the tank that you can get off eBay for 100.oo or so. that is built for the Shadow 1100.

I would love to have another option for a pump.There is one or two problems.the 1500 has very little extra space under the plastic to fit a pump and the carbs set higher than the tank.Will that External pump lift the fuel up out of the tank If I could find a spot up top for it?The pulse pump from a 1200 might fit the bill,it does have good suction and I've heard of a prelude external pump used for them.
All this makes me wonder why the car pump won't last long.isn't it designed to provide about the same pressure and flow as the bike?

I just installed the Honda Accord LX pump (on my 89 SE) and the only issue (so far) is getting the fuel tube from crimping when I drop the unit into the tank=easy fix. Regarding overheating, I believe that can be minimized as long as you don't run on empty as much as you normally would. If you're like me, at 1/4 tank I'm typically stopping to fill back up. So instead of having the luxury of running down to 1/8th or so, you will have to make a habit of refueling sooner.
I'm gonna try that and see how it goes. I'll make sure to post if it fails!

Put the Accord pump in my 89' 1500 this past weekend. Pumps fine so far, only complaint is that it is a tad bit noisier than the OEM.
