86 Aspencade Fuel Pump

Postby scrbowler » Tue Dec 14, 2010 3:02 pm



Can anyone tell me if the fuel pump from a GL1000 would work on the GL1200. It is a carburated engine on the bike.

Another question first would be is there anything that could be fixed on a fuel pump? The pump works fine it is just that when sitting and cold like in the mornings it leaks gas out of the pump itself for an undetermined amount of time. I ride 30 miles to work and when I come out to go home in the afternoon it does not leak. Not sure what that could be but if it is something that can be fixed I would rather attempt to do so.

thanks for the help and information

Steve

It could be a number of things - without pulling it apart, it's going to be hard to say. A GL1000 pump is likely not going to have sufficient flow for a GL1200. I don't even know if a GL1000 pump will fit on a GL1200, as it is a mechanical pump (the GL1200 uses an electric fuel pump), and is driven by the right camshaft.

GL1000

Fuel Pump Pressure
2.4 psi at cranking speed
2.3 psi at 1000 rpm idle
2.0 psi at 5000 rpm

Fuel Pump Volume
12 oz/min at 600 rpm
15 oz/min at 3000 rpm
17 oz/min at 6000 rpm

GL1200

Fuel Pump Volume
16.9 oz/min minimum

I appreciate the information. I will pull the pump off my bike tonight to see if I can find any visible signs of where it is leaking.

If you need to replace the fuel pump you can get one from an automotive parts store that fits a 1985 Honda Prelude 4 cylinder, carburated car, for @ $60. The physical size is larger than the OEM pump, but the pressures and volume are close to the original. Also, it will bolt up using the same mounting holes and fuel lines. I used one on my '84 Aspencade and everything works fine. My original pump began leaking also, and it wasn't long after that it just quit working.

thank you!! I will check into this as it is much cheaper than the OEM Honda Goldwing pump.

I appreciate the information.

The inlet and outlet tubes on the replacement fuel pump are a bit larger than on the original, but I replaced the fuel hoses and the new ones stretched to fit the replacement pump.

Can the leaking pump before it leaves you stranded. That's what happened to me in rather short order. Right before it died, clicked rather loudly, and got quite warm, leaking all the way. Some catastrophic failure of the internals I suppose.Obtained a replacement from a trusted source (used) but will replace mine with the Prelude pump when I do the Poorboy conversion.

It sure left me stranded....started and ran fine...went to a resturant to have breakfast...came out..started fine and ran until I got almost home...had to push it several blocks. By the way...I have some pictures posted of the chrome tail pipe extension I used to cover the fuel pump on an earlier post. just scroll down and you will find it.

Daljaz, I was waiting for you to chime in. What you did is exactly what I plan to do when I replace mine. Scrbowler, act now, the pump and the clock is ticking.

Patrick, the local Autozone here had to order the Prelude pump...so I will probably order another one for a spare to carry with me on long trips...if the pump fails sometime in the future, I will have an extra with me. At $60 that would be pretty good insurance.
